This is an article about Keira Knightley's breasts. Enough said, right, fellas?

Cleavage was one area the Pirates of the Caribbean star did NOT discuss in a recent Elle interview, but she still found time recently to comment on the treatment of her boobs on movie posters in America. The young star is annoyed that her shots are always photoshopped for the U.S.

"I don't have any tits, so I can't show cleavage," she bemoaned. "But you're not actually allowed to be on a magazine cover in the U.S. without at least a C cup because it turns people off."

The chest - and we use that term loosely - of Nicole Ritchie might disagree with that statement.

"Apparently they have done market research and found that women want to see no less than a C cup on other women. Isn't that crazy? So they make my tits bigger."

Knightley says market research in this country shows that men want to see women with no less than a C cup on their cover models. Those pigs!

On the King Arthur poster (pictured), Keira's chest was noticeably larger - but at least they asked her permission:

"Those things certainly weren't mine. I remember we had an interesting discussion when they said, ‘We want to make them slightly larger and you'll get approval', and I was like. ‘Okay, fine. I honestly don't give a shit'."

Neither do most men.
