Keira: OK to be flat

She refuses to get breast implants:

Twenty-three-year-old box-office babe Keira Knightley recently refused to have her boobs enhanced in publicity photos for her new movie "The Duchess."
"She is proud of her body and doesn't want it altered," a source told Britain's Daily Mail last week.

I'm with Bethan Cole: Fake boobs are unnatural. If Hollywood wants skinny movie stars, it can't expect them to be both skinny and buxom.
