Although Keira Knightley has lost lots of weight noticeably, she denies having any eating disorder.
Knightley appeared in a revealing gold dress at the premier of Pirates of the Caribbean 2 & she didn't even look slim, she looked kind of sick!
In her family, both her grand mother & great grand mother suffered from Anorexia, but when asked about her weight, she replied: Whatever people say about my weight that's all wrong!
She also said: Hollywood is all about the way you look, and I don't think that's the healthy thing for anyone. But, if you're strong and comfortable with yourself, then you're going to be fine.
