The stunning actress, who is currently shooting sex scenes with Sienna Miller for new movie 'The Best Time of Our Lives', bares her body so much she is worried there will be a backlash from fans.
Keira Knightley told Total Film magazine: "There are plenty of sex scenes in the book, so the adaptation is true to its source. I think soon, people are going to insist I keep my clothes on!
"I wouldn't do anything I didn't feel completely comfortable with. I suppose I'm very European in my attitude to my body.
"I'm an actress. I have certain tools. One of them is my body. I don't mind stripping off occasionally."
