Keira Knightly strips down on the cover of the mag -- on newsstands November 20 -- where she opens up about being comfortable with nudity (obviously), her upcoming wedding, and the ever-present argument over her weight.
"I'm quite rigorous about what gets exposed," the 27-year-old noted about baring it all in films. "No bottom half! I don't mind exposing my t-ts because they're so small—people really aren't that interested!"
On Her Wedding
The British beauty has been engaged to James Righton, keyboardist for the London-based band Klaxons, since May, and she's always tried to keep her private life private. So how will Keira break the big wedding news to the public?
"Maybe I'll be permanently engaged!" she jokes.
On Her Weight
The Oscar nominee has long been accused of being too thin or even suffering from anorexia, and all the talk definitely got to her.
"I knew I wasn't anorexic," she shared. "But maybe my body is somehow not right. Or my face is not right. Or the way I speak is not right. When you're going through a period where you're really getting a lot of criticism, you go, 'Maybe all this is right!' You just kind of want to hide it all."
Well she definitely doesn't hide it all in this spread!
