Israeli/American actress Natalie Portman has revealed that she had shied away from doing nude scenes in the past, as she was uncomfortable with them.

Portman, 28, who posed for the latest cover of V magazine, warned about her lesbian scene in Black Swan as being extreme.

And she also talked about how she forced the rewriting of the 1999 film Anywhere But Here after refusing to do a nude scene.

I was figuring out my own sexual identity, likes and dislikes and all that stuff, and its weird to be doing stuff on film as youre figuring it out, the Daily Telegraph quoted her as saying.

Also being a sexual object when youre a kid is really uncomfortable. After The Professional, I was already getting creepy letters.

Its annoying because online bullshit interferes with what I want to do artistically, she added.
