Kelly Clarkson Talks Weight Loss, Being a Blonde

Kelly Clarkson has been undergoing some serious makeovers as of late, and at Thursday night's Duets taping, Us Weekly got her to open up about her 30-pound slimdown.

"There's no secret!" the 30-year-old expressed to Us at the event held in CBS' studio in Studio, City, Calif. "It's just trying to eat a little better and work out a little more. But no matter what size I am I love performing no matter how big or little I am! I feel good."

According to an insider, the 5-foot-4 star decided to slim down for good after watching a recording of her December performance on VH1 Divas Celebrates Soul. "She saw how heavy she was and she didn't like it. That's when she decided to really get into shape," the source told Us.

But dropping several dress sizes isn't the only transformation the "What Doesn't Kill You (Stronger)" singer is excited to show off. On June 6, she traded her glossy brunette locks for a blonde hair color.

"I love it!" she told Us about her summer hair switch up. "People keep asking me if I am having more fun, being blonde, but I always have fun! Whether I'm blonde, redhead, or brunette! I always have fun, dammit!"

The two-time Grammy winner hasn't been having fun all by her lonesome, however -- she's been spending time with her boyfriend, 35-year-old Nashville-based talent manager Brandon Blackstock--the son of her manager, Narvel Blackstock, and Reba McEntire's stepson--since late last year.

"I'm too happy! He's ruining my creativity!" Clarkson, who is famous for her brokenhearted power ballads, joked to Us last month. "I'm writing all this happy sh--! It's killing me."

Tropic Thunder, indeed!

During the sun-filled last leg of his European tour with Jennifer Aniston, screenwriter/actor Justin Theroux, 40, went shirtless and revealed his sexy six-pack abs in Capri June 18. "Justin runs a lot" to stay in shape, a pal tells the new issue of Us Weekly of Theroux's stealthily chiseled body.

A dedication to fitness is just one of the many things Theroux and Aniston, 43, have in common. While staying in a $3,750-a-night room at JK Place in Marina Grande, the two frequently visited the hotel's gym, spa and pool.

Tattooed Theroux -- who kicked off his vacation with Aniston in Paris June 11 -- "sunbathed but didn't swim" aboard the $17,555-per-week Liberty of Lymington yacht the following day.

Tyra Banks Wears Sexy Swimsuit, Mocks Her "Big Forehead"

Tyra Banks is turning the tables.

Often ridiculed for the size of her forehead, the 38-year-old America's Next Top Model host uploaded a sexy Instagram photo of herself wearing a skimpy swimsuit June 25. "I challenge you to a big forehead contest!" she wrote in the caption. "You know I got that win on lock!"

Banks is on a mission to empower young girls to embrace the very qualities that make them special. "This is who I am! I'm Tyra Banks and I have cellulite!" she told Us Weekly at the Moth Ball in NYC May 8. "That makes me 'flawsome' because I own it as part of what makes me unique. Don't get me wrong: I don't think my cellulite is beautiful, but I think it's 'flawsome.'"

"My main mission is to get girls to realize their inner and outer beauty and have high self-esteem with both," she explained. "'Flawsome,' for me, is about being flossy, amazing and awesome with our flaws and celebrating those, too."

As the executive producer, creator and host of America's Next Top Model, the California native looks for contestants who exemplify what it means to be "flawsome."

"I try to do simple exercises, whether it's push-ups or sit-ups," Port shared with Us Weekly last month about maintaining her bikini body.

Soaking Wet Jessica Biel Reveals Amazing Beach Body

Jessica Biel was named Esquire's "Sexiest Woman Alive" in 2005, and by the looks of it, she's hoping to reclaim her title in 2012.

The Total Recall actress, 30, revealed her toned beach body in Puerto Rico June 22 while taking a dip in the Atlantic Ocean. Though Biel covered up with an O'Neill wetsuit, she showed off her long legs -- and perky booty! -- in string bikini bottoms. (The star's fiance, Justin Timberlake, 31, is in town shooting his new movie, Runner, Runner.)

How does Biel keep her body in tip-top shape? "For me, getting enough sleep, drinking lots of water, having a healthy diet, and staying away from alcohol are musts," she told ELLE in June 2011. "It's so boring, I know, but doing those things really helps."

Biel is also a fan of boxing, martial arts and yoga. "Yoga is a constant for me because it keeps my muscles long and flexible," she explained. "But now that summer's coming around, I'm planning on spending more time outdoors playing volleyball and jogging with my dog, Tina."

The actress also maintains a healthy, balanced diet, frequenting places like Real Food Daily, which specializes in organic vegan cuisine. "M Cafe is also great -- it has a lot of macrobiotic options," she told ELLE. "But you can find healthy food pretty much anywhere. I do a lot of cooking at home using grains and vegetables."

Timberlake proposed to Biel several months ago with an estimated $130,000 diamond ring. Together on-and-off for five years, the stars are in the midst of planning their summer nuptials, sources recently told Us Weekly. "It will be a big wedding. They have lots of people they want to invite."

Lauren Manzo: I Want to Lose Another 35 Pounds

Lauren Manzo's weight loss journey is far from over.

The Real Housewives of New Jersey star, 24, shed 20 pounds in seven months after getting a lap band on September 21, 2011. The surgery -- in which a silicone band is placed around the top part of the stomach to control food consumption -- was clearly a success, and in May, Manzo had the band loosened.

She dropped another 10 pounds by following a strict protein-and-vegetable diet and working out six days a week. In a recent Us Weekly interview, Manzo revealed she wants to lose another 35 pounds.

"When I hit 120, I'l decide if I want to go to 155," she explained. "I'm motivated. Hopefully, by the end of the summer, I'll be in a bikini. I've never worn a bikini in my life!"

VIDEO: Lauren vows to wear a bikini for the first time this summer

After years of yo-yo dieting, Manzo was thrilled to find a solution that works. "Getting the lap band was the best thing I've ever done in my life," she told Us. "I bought leather shorts at Betsey Johnson the other day. A size 10 was too big. The next size they had was a 6, so I was like, 'Forget it. They're not gonna fit me.' But they fit!"

New Mom Jessica Simpson Flaunts Major Cleavage During "Walk Around the Block"

Jessica Simpson sure loves her over-the-top Twitter photos!

On June 22, the new mom, 31, uploaded a new picture that puts her engorged breasts front and center. "Just taking a walk around the block," Simpson, who welcomed daughter Maxwell Drew on May 1, wrote. "Street legal?"

Simpson has been heavily focused on her appearance since becoming a first-time mom seven weeks ago. Her main incentive: slimming down as a part of a $4 million Weight Watchers deal.

"The cool thing about the program is that it focuses on healthy habits for the long-term (and I can still indulge in my guilty pleasures every now and then, too)," Simpson explained on her official Facebook page. "I have actually gotten a group of friends together who are going to be doing it with me."

Simpson, who is still engaged to Maxwell's dad, Eric Johnson, 32, has also given up fast food.

"She's breast-feeding Max and wants her to get the best nutrition," a source recently told Us Weekly of the singer, whose pregnancy snacks included butter Pop-Tarts and Kraft mac 'n' cheese. "She has to cut down on fast food. Besides, it's a great way to jump-start the massive diet ahead."

Jennifer Lopez, Jordin Sparks and More Celebs Reveal Their Weight-Loss Motivation

Losing weight is not an easy thing to do. And while it's ultimately up to you to drop those unwanted pounds, motivation to do so is often right in front of you. Here are some of Hollywood's biggest beauties who know this struggle all too well. Read on to hear their thoughts on their own weight-loss journey.

 

Jennifer Lopez 

"You get to the point where you're like, 'Where am I? What happened to me?' I got to get myself together for my kids, you know? They need to know what I really look like."

Always proud of her curves, the 42-year-old says it was her twins, Emme and Max, who inspired her to lose the 50 pounds she gained during her pregnancy.

 

Jordin Sparks 

"Every time someone sees a slimmed-down picture of me, it's not because I felt the pressure of the girl next to me being size 2. It's just making the choice for myself to be healthier, because I know that I'm less sick when I'm more active; I have more energy when I'm more active."

The Sparkle actress, 22, explains how the motivation behind her 30-pound weight loss was her health and not a desire to fit the Hollywood mold.

Ricki Lake 

"I am really getting in great shape. I will be wearing less and less clothing the smaller I get. I am feeling more comfortable in my own skin."

The former talk show host, 43, talks about how losing weight gave her a new sense of body confidence. Ricki lost 13 inches and 15 pounds during her first month on season 13 of Dancing with the Stars.

Jennifer Hudson

"I'm prouder of my weight loss than my Oscar!"

The 30-year-old mom to son David, 2, should be proud; thanks to hard work and the help of Weight Watchers and celeb trainer Harley Pasternak, she lost a total of 80 pounds and gave her life a total 360.

Jennifer Love Hewitt

"For the most part, yeah, I'm happy with my body, but there are days when I'm like, 'Ugh! Really? Why is it so hard to fit into my jeans?' That's when I say to myself, 'I look this way because I'm supposed to. If we all looked the same, we'd be boring.'"

The Client List star, 33, talks about being at peace with her body. Hewitt's no stranger to being under media scrutiny when it comes to her weight. After years of ups and downs, she has adopted a fitness program and healthy diet that is easy -- and fun! -- for her to maintain.

Kelly Osbourne

"If you want to lose weight for good, you need to make a commitment to a life change. You have to say, 'I'm just not going to eat that anymore. I'm going to change my bad habits.' Otherwise, you'll spend the rest of your life yo-yoing and you'll be miserable. By no means is it easy. Getting in shape is one of the hardest things I've ever done."

Osbourne, 27, is one of the biggest weight-loss success stories to come from DWTS; she lost an amazing 42 pounds! After the show ended, the E! correspondent kept up a regular fitness routine and stuck to a healthy diet. She knows that weight loss is about making a total lifestyle change.

Head over to FitSugar to hear from other stars who've dropped the weight.

Lauren Manzo: Seeing My Weight Struggle on TV Is "Hard"

Undergoing lap band surgery in September 2011, 24-year-old Lauren Manzo has no regrets about sharing her weight loss struggle this season on Bravo's Real Housewives of New Jersey. In fact, it was Caroline Manzo's daughter's own decision to go public with her battle of the bulge.

"It's hard seeing yourself on TV. The camera doesn't add 10 pounds, it adds 800 pounds!" reasons Lauren, who had gone through years of yo-yo dieting and tried programs like Jenny Craig, Weight Watchers and LA Weight Loss to try to shed pounds. Tipping the scales at 185 pounds, the makeup store owner decided to undergo surgery -- and initially kept it a secret from RHONJ audiences.

"When I first got it, I didn't want to tell anybody. So many fans related to my struggle, I didn't want to feel like I was letting them down," Lauren tells Us. "I've gotten such a great response. It's worth it."

Lauren tells Us that her mother, Caroline, may have doled out tough love on TV -- calling her daughter "8 pounds of sausage in a 5-pound bag" -- but argues that her criticism motivated her, and didn't offend her. "If I my mom weren't so blunt with me, I wouldn't be as happy as I am today," Lauren says. "I know she didn't mean anything by it. She has always told me I am beautiful -- my father and brothers, too."

VIDEO: Easy-to-follow summer diet tips

Intending to lose at least 35 more pounds, Lauren has not yet settled on a goal weight -- and is anxious to show off her bangin' new bod this summer at the beach.

"When I hit 120, I'll decide if I want to go to 115. I'm motivated," explains the reality star. "Hopefully, by the end of the summer, I'll be in a bikini. I've never worn a bikini in my life!"

Stacy Keibler Shows Off Sexy Six-Pack Amidst Pregnancy Rumors

Despite reports to the contrary, Stacy Keibler isn't carrying George Clooney's child -- as her first official Instagram photo proves.

Though the model, 32, hasn't addressed the pregnancy rumors herself, a source tells TMZ they are "100% false." And on June 20, Keibler -- who is vacationing in Como, Italy with Clooney, 51, at his famed estate -- uploaded a photo of herself in the gym. With a dumbbell in hand, the model showed off her sexy, sweaty six-pack abs in a white sports bra and black yoga pants.

To get her bangin' bod, Keibler constantly changes her workout routine. "I go to Barry's Bootcamp, I go to Physique 57 -- every week is different for me," she told Us Weekly earlier this year. "Sometimes I'll go to Barry's three times a week because it fits into my schedule better, and sometimes I'll work out with a trainer five times a week."

VIDEO: Behind-the-scenes of Stacy Keibler's Us Weekly photo shoot

She added: "I also like boxing. That's an amazing workout. . . Summer is when I start getting in the groove of at least once or twice a week mixing in something like boxing. I just like to mix it up."

Keibler, a former Baltimore Ravens cheerleader, has always been athletic. "I started dancing and playing sports at a young age, and then I got into cheerleading and I've always had that," she told Us. "But even at 15 I was going to the gym. I've just always been conscious of being healthy and I'm really very balanced. I like to eat a lot so I have to work out a lot to balance it out."

Real Housewives of New Jersey's Lauren Manzo Lost 30 Pounds!

Lookin' good, Lauren!

After years of yo-yo dieting, Lauren Manzo's battle of the bulge became a major plot point on the current season of Real Housewives of New Jersey -- and she suffered cruel comments at the hands of anonymous Twitter followers.

"I hated myself," the 24-year-old, 5-foot-3 owner of makeup store Cafface tells Us Weekly exclusively. "I was depressed." At her heaviest, she weighed 185 pounds.

So, last September, Manzo finally followed the advice of concerned parents Caroline and Albert and underwent lap band surgery -- in which a silicone band is placed around the top part of the stomach to control food consumption. (Her dad Albert had the surgery back in 2008).

Losing 20 pounds over the next seven months, Manzo had the band loosened in May -- and dropped another 10 by following a strict protein-and-vegetable diet and working out six days a week. The Bravo star (who's been dating Vita Scalia for three years) hopes to lose 35 more pounds.

Showing off her incredible new shape to Us, Manzo says she feels "amazing. Getting the lap band was the best thing I've done in my life."

She admits to Us that she initially kept the lap band surgery secret. "So many fans related to my struggle," she says. "I didn't want to feel like I was letting them down."

She cautions of the device: "It's not a miracle button that lets you eat whatever you want . . . I wanted to try to lose weight on my own for a while."

And, indeed, although Manzo avoids salt, sugar, carbs and fat with her new diet regime -- and endures intense sessions with trainer Guy Del Corso -- she still loves to eat.

"I like food," she explains. "I can't drink liquid egg whites for the rest of my life. So I've learned a lot of great ways to cook now . . . I have great willpower."

Her ultimate goal? "Hopefully, by the end of the summer, I'll be in a bikini. I've never worn a bikini in my life!"

Kate Upton Flaunts Major Cleavage, Seductively Licks a Popsicle

Kate Upton is anything but subtle.

The buxom blonde appears on the cover of GQ's July issue, where she seductively licks a lollipop while wearing a $30 red, white and blue bikini by O'Neill.

The racy pictorial is nothing new for Upton, who also models a drenched white T-shirt and a salmon-colored Laura Urbinati bikini, Carrera sunglasses and Christian Louboutin heels. The single star even suffered a wardrobe malfunction while shooting with photographer Terry Richardson, 46.

"For the GQ photo shoot, we were on that ride where the seat spins while the actual ride is spinning, and I'm wearing a one-piece. And all of a sudden the whole entire top falls off!" she says. "I'm holding myself, laughing, turning bright red, but a lot of people are watching, so they kicked us out of the Santa Monica Pier -- it was so embarrassing."

She adds, "You wouldn't think that would happen with a one-piece!"

Despite receiving criticism for her hyper-sexualized persona, Upton is happy to show off her hot body in photos. "It's like any job," she says. "You find your strengths and play them up."

Chris Hemsworth vs. Joe Manganiello: Whose Shirtless Beach Body Is Hotter?

Battle of the blonde and brunette beefcakes!

Chris Hemsworth, star of The Avengers and Snow White and the Huntsman, showed off his six-pack abs and bulging biceps at the Park Hyatt Hotel in Sydney, Australia June 18. The actor and father to India, 5 weeks, added 20 pounds of muscle to his 6-foot-3 frame to play the titular role in 2011's Thor.

To become the hammer-wielding superhero, Hemsworth, 28, worked with trainer Michael Knight, who told Men's Fitness he devised "a bodybuilder-type protocol focused on high-weight, low-rep moves designed . . . [and] total-body circuits designed to shift his excess fat while maintaining muscle."

VIDEO: See Chris Hemsworth in action in The Avengers

Hemsworth admitted that although his workouts with Knight were "exhausting," they were well worth it. "I prefer to be training than not. It gives me more energy and I just generally feel better about myself," he told the magazine. "I feel like I've earned that beer at the end of the week."

Hemsworth wasn't the only buff star to show off his sexy, shirtless body this weekend: Joe Manganiello, 35, stripped down in Miami Beach June 17. The actor, who plays an exotic dancer named Big Dick Richie in Magic Mike (in theaters June 29), is no stranger to taking off his clothes, thanks to his role as a werewolf on HBO's True Blood. To look good for nude scenes, Manganiello exercises twice a day, six days a week.

VIDEO: Joe Manganiello tells Us how he stays in shape

"My trainer, Ron Matthews, is the best in the business. So I pay him money to kick my ass!" the actor told Us Weekly in 2011. "It's a brutal 60 minutes three times a week, and then the other nine workouts are on my own."

How Courteney Cox, 48, Stays in Shape

Happy Birthday, Courteney Cox! The actress turns 48 on Friday, and to celebrate, we're taking a look at her fit philosophy. Here's how the actress and mom stays in shape.

In her own words: Cox says it best -- "My fitness philosophy is to be active in life and enjoy what I am doing," she shared in Gwyneth Paltrow's Goop newsletter. "I have always loved exercise and feel that being active is important to maintain not only physical health, but mental health as well."

In action: The Cougar Town actress is a devotee of the famed Tracy Anderson Method. Cox says she loves the celebrity trainer's workouts because they're a "constant challenge." "As soon as I have mastered a certain exercise, they throw something else at me," she says. "In my hour-and-a-half workout sessions, I have had a mental challenge and a physical challenge." Cox has also professed to being a fan of the Power Plate. Whether she's seeing her trainer or paying tennis on the weekend, she tries to incorporate regular cardio almost every day of the week.

Her diet: The mom to Coco Arquette, 7, is rumored to be a fan of the blood type diet, based on the book Eat Right For Your Blood Type. While experts have warned that the fad diet's principles aren't based on scientific proof, the book promises weight loss if you stick to diets tailored for your blood type. Cox also says she follows a low-carb diet, drinks lots of coconut water, and avoids caffeine.

HOT! James Marsden, Josh Hopkins Reveal Buff Beach Bodies in Hawaii

The only thing hotter than the 84-degree temperature in Hawaii Thursday? The sight of shirtless stars James Marsden and Josh Hopkins.

The best friends took time off from the Maui Film Festival June 14 to enjoy a day of fun in the sun. Marsden, 38, and Hopkins, 41, revealed their buff beach bodies, while taking a dip in the Pacific Ocean. How does Marsden -- a single father-of-two -- stay fit in his late thirties?

"The gym mentality doesn't work for me," he tells Men's Health. "It's too isolating. I have to be outdoors chasing a ball. And I feel substantially better about myself when I do."

He adds: "You want to look good, but it's not necessary to look like the statue of David every time you take your shirt off. I'd rather look healthy, have a sound mind, and be comfortable in my own skin."

Marsden isn't afraid to indulge in a few guilty pleasures, either. "I like eating Hershey's chocolate and Jif peanut butter!" the Bachelorette actor told Us Weekly in 2011. "That's it!"

Cougar Town star Hopkins -- who stands tall at 6-foot-3 and weighs 200 pounds -- tells Men's Fitness he's "naturally more muscular than skinny," so he has "to do a lot of cardio to keep my heart rate up." Like Marsden, he prefers playing sports to stay active. "I like that endorphin rush. I think that just stayed with me."

Emily Maynard Had Boob Job Before Competing on The Bachelor: Source

Emily Maynard may seem like a low maintenance single mom on The Bachelorette, but before getting her big break on 2010's The Bachelor, the sweet southern gal went under the knife to prepare for her close-up, multiple sources tell Us Weekly.

Undergoing plastic surgery -- she now has breast implants, veneers and likely a nose job -- before taking part in Brad Womack's season of the ABC hit, Maynard spruced up her appearance in hopes of landing a hot husband.

Why the drastic cosmetic enhancements? One source tells Us Weekly Maynard, 26, developed aesthetic insecurities after developing Bell's palsy as a teen. The nerve disorder left "the right side of her face paralyzed for a few months," continued the insider. "She was tormented in school."

Though her Bachelorette suitors declared her "amazing" and "gorgeous" during her season's May 14 premiere, some close to Maynard believe she took her beauty quest too far. A friend of Womack's who met Maynard when the two were still engaged is struck by her appearance now: "Her expressions seem kind of frozen," says the pal. "It looks like Botox."

VIDEO: Emily and Brad's bitter breakup

Once she revamped her look, Maynard demanded a big fat paycheck in order to take part in The Bachelorette -- after publicly declaring she'd "never" sign on.

"Emily told [producers] she wanted $750,000," says a source close to the stay-at-home mom, who receives financial support from her late fiance NASCAR driver Ricky Hendrick's parents. "They said no way, but she settled for something higher than $100,000, probably around $150,000."

(In contrast, says the source, Jillian Harris and Ashley Hebert were paid $50,000 and $30,000 respectively).

When Maynard was tapped to be the Bachelorette after she and Womack split in June 2011, "she got difficult," a show source explains. "She knew she was the star, so she became a bit of a diva."

Argues a Maynard insider: "She is painted in this Mother Teresa light. She is a nice girl, but she isn't as good as she is made out to be."

PIC: Jessica Simpson Gives First Glimpse of Post-Baby Bod

Go, Jessica, go!

Jessica Simpson isn't kidding about dropping the pounds gained during her very first pregnancy with daughter Maxwell Drew Johnson, now one-and-a-half months old.

On Tuesday, the 31-year-old Fashion Star mentor was once again spotted hitting a gym in Los Angeles -- and this time, after the workout was done, photographers caught the very first glimpse of Simpson's shrinking post-baby figure.

Heading back into a waiting SUV, Simpson (engaged to Maxwell's dad Eric Johnson) wore black leggings, tracksuit hoodie top and cross-trainers.

The singer and fashion mogul was first spotted hitting the private gym of celeb trainer Harley Pastermak (who has worked with Halle Berry, Hilary Duff and others) last week. The 5-foot-3 star told ELLE magazine that she weighed 170 pounds at the time of her iconic pregnant nude photo shoot for its April cover. After Maxwell's birth (the little girl weighed 9 lbs 13 oz), Simpson needed to heal from her C-section -- and then it was back to the gym.

An extra motivation: A $4 million deal with Weight Watchers.

"She hasn't even thought about working out for a year!" a source told Us Weekly last month. "But if she wants this, she'll need to work out a good five days a week."

Rihanna Shows Off Bare Midriff in New Vita Coco Campaign

Rihanna is proof that coconut water does a body good!

In her new ad campaign for Vita Coco, which was shot by famed photographer Terry Richardson, the "Where Have You Been" singer shows off her bare, toned midriff, which she attributes to her recent diet and coconut water!

"I wasn't drinking enough water before, and I love coconut water," the Vita Coco celeb spokeswoman tells Us Weekly. "It hydrates me just as much as regular water so it really started to affect my diet and the way my body was shaping up."

"I also started to eat a little differently" the songstress admits, delving into the details of her diet. "I added one vegetable to each meal with my diet for awhile -- but then I went right back to eating McDonald's and pasta and stuff like that too! So really its just having a balance of eating great and staying hydrated."

In the photos, the Barbados beauty flaunts blonde hair and sports a custom-made ensemble adorned with pineapples that shows off her slim legs and flat stomach.

"I never weighed myself so I don't know how much weight I was to know how much I lost," the singer, 24, tells Us, adding that she has noticed that she has dropped two sizes. "I haven't worked out sine January!

Rihanna's sunny new campaign for Vita Coco was unveiled on Monday, and fans can expect to see the singer's ads all over this summer.
