Keira Knightely has revealed that she doesn’t like to cover her breasts with a bra while filming a sex scene and would like to do the scene with bare breasts.

She explained, “I always bare my breasts - not just in this film.

“I never like sex scenes when I’ve got a bra on, thank you very much.”

However the 23-year-old actress finds singing more terrifying than displaying her bare breasts.

The actress added, “That was terrifying. I wasn’t particularly expecting to sing.”

“I was like a pre-pubescent boy. My knees were shaking but a couple of shots of vodka and everything was OK.”

Keira also applauded her mother, Sharman Macdonald for adding a sex scene in her new flick The Edge of Love.

She said, “She dared to put a sex scene in it. It didn’t worry me that my mother knows what sex is.”

“Come to think of it, I was found under an apple tree. My mother is a virgin. I had no hissy fits when she presented me with the scene”

Well it doesn’t matter if Keira bares her breasts they are very small to turn on a man.
