Keira Knightley Feels Lucky She Did A Sex Scene

Keira Knightley feels "liberated" filming sex scenes.

The 22-year-old actress - who first bared her breasts when she was just 15 in 'The Hole' - says stripping off for her steamy love scenes with co-star Edgar Ramirez in 'Domino' was easy.

She said: "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."

Keira - who also appears topless as the wife of a 19th century silkworm smuggler in new movie 'Silk' - used a bottom double in 'Domino' because she is insecure about her butt.

However, Keira is proud of her perky breasts and is always happy to show them off.

She said: "I did have a body double for my bum but not on my top. I don't have a problem with that."

Keira - who had her cleavage digitally enhanced for the 'Pirates of the Caribbean' promotional posters - was also reportedly so unhappy with her "ugly" feet she had a foot double for her latest film 'Atonement'.

A source said: "Keira's feet were too big and veiny. She thought it was really funny."
