It's her bum or is it?

Kiera Knightly hates her bum which is why she used a body double for some of her scenes in the new movie, "Domino", opening in theaters this weekend. There's one scene in particular where her character has to give a man a lap dance where her body double was needed.

Some quotes from Kiera about her bum: "No, It's definitely a body double, I don't have that body. What a bum! I wish I had that bum! No, it was fantastic."

But as early as this year she vowed never to show her bum: "You're not going to see my arse! The top half is fine but the bottom half isn't."

Kiera's rationale? She thinks her butt is too big a la J. Lo. Quoted in Glamour magazine earlier this year, Kiera said: “Believe me, I have a J.Lo bum!”

Here she is looking fantastic at the premiere of her new movie, "Domino". Who's the hot guy?
