The shapely mother of two regularly crops up on best-dressed lists for her figure-hugging dresses, which show off her classic hourglass figure. But as a schoolgirl, the body comments she received from peers, like the nickname "Blubber," were nothing shy of cruel.
As she got older, the taunting went from school children to the media – even when she was supposedly on top of the world with box office hit, "Titanic."
"Things happened in quick succession between the ages of 19 and 22. No wonder I blew up like a balloon. Remember those days? I think it was the Golden Globe year for 'Titanic,' and I was on a red carpet and somebody showed me a picture and I was like, 'F***, I was enormous,'" she told the mag. "I don't particularly remember sitting at home crying and eating endless packets of [British cookies] HobNobs. I don't remember doing that at all. Honestly, I think it was a stress thing or something. I don't know."
Happy for her size at the age of 33, Kate has been stunning the world's media with her red carpet poise, and voluptuous figure. But while she was lauded for looking elegant at the Oscars earlier this year in a gray one-shouldered floor-length Yves St. Laurent gown and made waves after posing partially nude in the December 2008 issue of Vanity Fair, Kate still doesn't think of herself as a bombshell.
"Even now I do not consider myself to be some kind of great, sexy beauty," she told the magazine. "Absolutely not."
Perhaps one reason she isn't ready to wear the "sexy woman" tag is due to her commitment to let young people know that magazine covers and spreads are Photoshopped, as are films.
"I do think it's important for young women to know that magazine covers are retouched," she noted. "People don't really look like that. In my films I might look glamorous, but I've been in hair and make-up for two hours."
Despite the success, including her first Oscar, which she received in February 2009 for her role in "The Reader," Kate still can't get away from the thoughts of being bullied for her figure as a young woman.
When asked if she still sees herself as the fat kid in school, Kate said, "Yeah."
"I was the girl that people would always say, 'Ah, it's such a shame, because you've got such a pretty face.'" Kate said.
