It's the seventh time Keira has peeled off on film.
She said: "I never like sex scenes when I've got a bra on, thank you very much."
Couldn't agree more . . .

She's beautiful. It's not all about the breasts! Get over yourselves men. At least, she didn't put implants in.

Good for you Keira, you have not gone for the super sized implants, you look lovely and how a real woman should look... Nothing looks worse than a woman with a couple of grapefruits stuck to her chest. Yuk Yuk... lets hear it for real woman.

Despite her tiny ****, she looks pretty good. Cillian looks fricking awesome. How hot is he.

she is an absolutely stunning woman who's eyes i could look into for a million years. she has a perfect body and can't understand people bitching about her.
get a life guys (and gals of that nature). Take a good look at yourself before you cast that stone. She's probably achieved more with her young life than you ever will.

Comments no doubt made by men with perfect figures - not. Give the girl a break.

Why is the nipple in the picture but blacked on in the sample movie! Strange!!!

She's completely flat chested. It would be liking being on top of a skeleton!
