Keira Knightley says she has no problems with big screen sex scenes – she even feels “liberated” by them.

She says, “Sex scenes are easy. I don’t really have a problem with them. Actually it’s quite liberating in the movie Domino to be out in the middle of the desert completely topless with a beautiful Venezuelan guy. I was very lucky.”

However, Knightley admits that whilst her real breasts are seen on film, she gets someone else in to pretend to be her nether regions.

“I did have a body double for my bum but not on my top. I don’t have a problem with that,” she confesses.

British actress Keira Knightley is taking legal action against a British newspaper, claiming an article it published suggests she has lied about having an eating disorder.

The Daily Mail included a photo of the star on a beach, alongside comments describing her skinny physique, as part of an article about a girl who had died of anorexia.

In a statement from her lawyers, Knightley vows to challenge the alleged implication she’s in some way responsible for the girl’s tragic death and the alleged suggestion she’s lied about having an eating disorder.

On a Pacific island holiday with lover Rupert Friend, the 21-yearold actress cut a waif-like figure on the beach. she carelessly frolicked in her skimpy bikini.

Only last summer, the Pirates of the Caribbean star emphatically denied that she suffered from anorexia.
