These 13 Hot Celebrities Were Once Chubby—Check Out These Shocking Slimdowns!

Who remembers when Gwen Stefani, Jennifer Hudson, and even Henry Cavill were chubby? Probably nobody, because it was that long ago. But check out these 13 celebs who used to be heavy as teenagers and had major slimdowns!

Let this photo be a reminder to not laugh at the nerdy looking girl growing up. She may turn into a gorgeous vixen!

That was of course Amber Rose, who has since lost the nerd glasses and replaced them with some fashionable shades. 

Who can forget Kelly Osbourne's chubbier days?

Check out Jennifer Hudson as a young teen!

Though she is slim now, thanks greatly to the Weight Watchers program, she wasn't always. In the past, Jennifer revealed however that she was "the skinny one" in her family as a kid, though she wore a size 16 during her teen years. "That was normal in Chicago," she said. "But then I'd go to another city, and it was real culture shock. I'm like, Huh? Wait a minute — I'm a big girl?"

Jerry O'Connell reveals he has been known “as the fat kid from Stand By Me.” But look at the former child star now!

Guess who this is?

It's really hard for us to believe this one, but Henry Cavill, aka Superman, was once overweight! In 2013 he said, “I was a fat kid so I was an easy target. ‘Fat Cavill’ was the nickname, which was a totally fair nickname, because I was fat.” Well, look at him now!

Kate Winslet may be a curvy beauty these days, but back in 2009 she told the U.K. edition of Marie Claire that she was nicknamed “Blubber” at school. She told the magazine, “I was bullied for being chubby.”

In 2010, Jillian Michaels admitted she weighed 175 pounds at her heaviest. "Being big as a kid was pure hell," the 5-foot-2 1/2 trainer told Redbook. She began gaining weight at age 12 after her parents announced their divorce. "I spent all of eighth grade in my classroom because God forbid I ever left. I was terrorized."

Funnyman Russell Brand was once chubby, and went to extreme lengths to drop the pounds. He admitted in 2006 to making himself sick. “It’s awful to be bulimic but I lost a whole lot of weight when I needed to,” he says. “I was a fat kid, not obese but chubby.”

One look at these ripped muscles and it’s very hard to believe singer Craig David was once overweight, but it’s true! David once said he was a “fat kid growing up” who “lost the weight,” adding, “But there’s always a fat kid inside that’s reaching out for Kentucky Fried Chicken.”

She may be quite thin these days, but yearbook photos reveal Julianne Moore was once a chubby-cheeked teen!

Khloe Kardashian has definitely had one of the most shocking slim-downs to date!

She spoke about her weight on Instagram earlier this year, saying, "People love to call me the fat one but as weird as it sounds I still don't think I would consider myself fat back then. Definitely overweight and unhealthy, yes." And now she's competing with her sisters for most fit body!
