Nicole Kidman has no problem with nudity

Oscar-winning actress Nicole Kidman says she doesn't mind going nude for the camera as long as the script calls for it.

The 44-year-old, who is now married to singer Keith Urban, has done a few sex scenes in new movie "Hemingway & Gellhorn", which features her as journalist Martha Gellhorn and actor Clive Owen as author Ernest Hemingway.

"The sex was very important in that relationship because that's the way she cuts Hemingway off," thesun.co.uk quoted Kidman as saying.

The actress admits the scenes were intense and she did question the director if they were indispensable for the movie.

"I kept asking Phil Kaufman, the director: 'Is all this sex important for the story? I wanted to make sure he wasn't just getting off. But these were two people who could make love when a building was falling down around them. They had passion," she added.

The film follows the relationship between Hemingway and Gellhorn.

Nicole Kidman says she doesn't let her insecurities affect her performance.

"Maybe as I get older, and now having had a baby, it might be different, but I enjoy not letting my issues get in the way of a performance. Once I start putting all my little insecurities in my mind, I'm not actually acting," she said.

"Then it's about me - and it should never be about me. It should be about the character," she added.
