Keira Knightley loves being naked in movies and thanks her British upbringing for her liberated attitude.

The 20-year-old actress stripped off to shoot steamy sex scenes in new movie DOMINO with hunky co-star Edgar Ramirez.

She says, "I'm British, so the whole sex scene, and being topless is fine.

"In fact, to be able to do that in the middle of the desert was actually quite liberating. And to do it with a beautiful Venezuelan - well, let's just say I'm a lucky girl!"
