London, Jan 8 (IANS) Natalie Portman has decided not to strip on screen because she doesn't like seeing her pictures on porn sites.

The actress partially stripped for a lovemaking scene in 2007 movie 'Hotel Chevalier' and it ended up on porn sites.

'It really depressed me that half of every review on the film was about the nudity. It made me think I shouldn't have done it,' imdb.com quoted Portman as saying.

'I'm not prudish about nudity. I think it's beautiful in films, and sex is such a big part of life. My issue is that I feel it takes something away from what you're doing when the focus is put on the wrong thing. My picture ended up on porn sites, and that's the dilemma,' she added.

The experience left Portman shaken and now she has decided not to do such a scene again.

'I just don't want to do something that will end up as a screen grab on a porn site,' she said.
