The skinny actress is very upset about the fact that producers always enlarge her breasts when it comes to movie posters and magazine covers. Keira is actually very happy about her modest assets and content with the slim figure that made all people suspect she might suffer from anorexia.

Keira said that she is sick of seeing her face over a pair of computer enhanced breasts that are not hers, in every poster for every film that she stars in. But, she claims, a policy among photographers is not to publish pictures with women who wear less than a C cup.

'I don't have any tits, so I can't show cleavage. But you're not actually allowed to be on a magazine cover in the US without at least a C cup because it turns people off'. Keira further said that this decision comes from a market research that clearly shows that other women refuse to look at famous actresses and stars with small breasts.

Knightley's boobs were exaggeratedly enlarged for the first time for the 'King Arthur' posters. She played the part of warrior Guinevere in it and, apparently, the producers were not happy about her small breasts.

'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 s**t".'
