Keira admits she's always got her boobs out...

Keira Knightly wasn't shy when she had to get her boobs out in her new movie The Edge of Love. In fact, she says she's used to it!

The little streaker admitted to People magazine, "I always bare my breasts. It's not like it's only in this film!"

And there we were thinking she was a boring old prude. Just shows you never can judge a book by it's cover!
