Keira Knightley Loves to Be Naked

Here's some good news for the fellas (and lesbians): Keira Knightley loves being naked.

She exposed her butt in her latest film, and she says it's becoming a habit. "I always bare my breasts," she said at the press conference to promote The Edge of Love Wednesday at the Edinburgh International Film Festival. "It's not like it's only in this film!"

Knightley, who hails from Britain, is best known in the United States for her role as Elizabeth Swann in the Pirates of the Caribbean series. Last year she appeared nude in her Oscar nominated drama, Atonement.

When talking about her sex scene with onscreen husband Cilliam Murphy in The Edge of Love, Knightley said: "It was very simple. It was a sex scene and I never like them when they've got bras on."

When the director of the film asked her to remove her bra, Knightley was game: "I said, 'All right then.'"
