Formerly-Slim Celebs Who Gained Massive Amounts Of Weight

Britney Spears

This star broke onto the music scene as a teenager with blonde hair and an hourglass figure. Sadly, her career fizzled among run-ins with the law, stints in rehab and broken marriages.

Now she’s doing a regular Vegas show, and her demanding schedule has caused her to pile on the pounds. She’s still seriously beautiful, but it might be time for a style change – the bra and undies look isn’t super flattering.

Kelly Clarkson

This American Idol winner has been criticized for her weight gain, but she isn’t letting that bother her. Recently she told Ellen “we are who we are, whatever size”. So true.

Vince Vaughn

Ladies aren’t the only ones who get criticized for piling on the pounds. These days Vince Vaughn is more dad bod than hot bod, but he’s still got that killer sense of humor that sucks us in.

Christian Bale

This guy is famous for his ability to put on and drop weight for roles. He committed to his largest weight gain ever for American Hustle, and pulled it off with ease.

We’re amazed that he goes to such lengths for roles, but seriously Christian, this can’t be healthy.

Steven Seagal

This actor, director and martial arts legend was made of muscle at the height of his career. Since then, he’s let himself go a little.

Now at 63, Seagal isn’t looking his best. He could probably still kick our butts though.

Val Kilmer

Val Kilmer was once everyone’s favorite chiseled hunk, but lately his weight’s been fluctuating, apparently because of a health condition.

After putting on a huge amount of weight, Kilmer spent 2014 slimming down so that he was the appropriate size to play Mark Twain in an upcoming movie, something he’s announced as his “dream role”.

Jessica Simpson

Jessica’s had on-and-off weight problems all through her career. She got into top shape for her role in Dukes of Hazzard, but she found the size hard to maintain. She also attracted media attention for her 70-pound weight gain during her first pregnancy.

She jokes that her weight gain is her husband Eric Johnson’s fault. He always tells her she looks great, no matter what size she is.

Matt Damon

Matt’s maintained a sexy body throughout most of his movie career, which was why it was so shocking to see him 30 pounds heavier in The Informant. He had to pile on the pounds for his role, and says that he found it really easy.

He’s working hard to lose it now, especially with a new Bourne film coming up. He’s taken up boxing, but right now describes himself as “the Sexiest Man Alive’s chunky cousin.”

Carrie Fisher

Carrie Fisher was once every boy’s dream girl. Then she stopped acting, fell out of the spotlight and developed some not-so-healthy eating habits.

She’s recently dropped 40 pounds and she’s getting ready to reprise her role as Princess Leia in the new Star Wars movie.

Marlon Brando

Back in his prime, Marlon Brando was the ultimate sex symbol. He was also a talented actor, winning Oscars for his performances in The Godfather and On the Waterfront.

Then he got older, and his eating habits got out of control. It’s rumored that in one sitting, Brando devoured 12 Burger King whoppers, two whole chickens, five gallons of ice cream and six hot dogs. At one point, he weighed 350 pounds.

Mark Hamill

Like Carrie Fisher, Mark Hamill let himself go after the buzz from Star Wars had subsided.

For Star Wars Episode VII, both actors have been supplied with personal trainers and top nutritionists, so they’ll be looking their best when they start filming.

Mariah Carey

Mariah Carey was a goddess in her youth, with the voice of an angel and the body to match. A slim figure is harder to maintain the older you get, and as the stress from Mariah’s hectic tour schedule piled on, so did the pounds.

These days she’s happy and healthy with her new beau James Packer and her kids.

Brendan Fraser

Brendan’s six pack is one of the main reasons he looked so good swinging through the trees in that loin cloth. In his current shape, we’re glad he’s not parading around in scraps of fabric anymore.

Keely Shaye Smith

Keely’s more commonly known as Pierce Brosnan’s wife, and when she first stepped out on the red carpet she sported a stunning hourglass figure.

Now, after giving birth to two children, she’s looking curvier than ever, but she still knows how to rock a bikini like a pro.
