Keira Knightley has no qualms about stripping off on screen because she is "not prudish when it comes to nudity".
The British actress has taken her clothes off on camera for films including The Duchess and The Edge of Love and she insists she is not embarrassed to bare all for a role.
She tells British newspaper The Mirror, "I'm not prudish when it comes to nudity. If the role calls for nudity, then I'm going to be naked. I'm not afraid to expose myself that way."
However, Knightley, who is engaged to Klaxons rocker James Righton, is adamant she finds love more difficult to fake than passion.
She adds, "I'm much more worried about revealing personal sides to myself, which I find harder to do. The hardest thing to capture about love is the actual physical intimacy between two people.
"The way two people behave when they are next to each other and touching each other, holding hands, resting your head on your partner's shoulder. In your personal life, you generally don't think about the fact you're touching your partner. That's a difficult thing to capture on film."
