Keira Knightley is a beautiful British babe who came to our attention as Elizabeth Swan in the Pirates of the Caribbean movies. She'd been acting for quite some time before that but she broke out in the swashbuckling adventure. Then we couldn't keep our eyes off of her. Luckily for fans of nude celebs she's done a great many scenes where her clothes come off, including an intense love scene in Atonement where you get to ogle plenty of boob. She's very young still so there's a lot more where that came from.
