Keira Knightley is busy promoting her new film in the UK. After working "The Edge of Love" world premiere at the Edinburgh International Film Festival, while hand-in-hand with costar Sienna Miller, on Wednesday, Knightley drew gasps on Thursday's London premiere, because of her jutting collar bone. But her clavicle isn't the only body part drawing attention, thanks to some love scenes in the film.

"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!"...

Referring to a scene in the wartime romance The Edge of Love with her onscreen husband Cillian Murphy, Knightley said: "It was very simple. It was a sex scene and I never like them when they've got bras on."

So when the director asked her to remove her bra, "I said, 'All right then.'"

The film was written by Sharman Macdonald, Knightley's mom, who also wrote a singing scene in for her daughter.

"I wasn't particularly pleased that Shar put singing into the script - in the first couple of takes I sounded like a a pubescent boy," says Knightley, who calls her mom Shar and instead of mother.
