Natalie Portman has branded her lesbian sex scene "extreme".
The 28-year-old actress - who has previously admitted she would consider embarking on a same-sex romance - insists there is nothing sexually compelling about the romp with Mila Kunis in new movie 'Black Swan'.
She said: "It's not raunchy - it's extreme".
The former child star - whose first big-screen role was in 'Leon' aged 13 - previously refused to strip-off the camera because she hadn't worked out her own sexual preferences.
She told America's V magazine: "Previously I was figuring out my own sexual identity, likes and dislikes and all that stuff, and it's weird to be doing stuff on film as you're figuring it out. Also, being a sexual object when you're a kid is really uncomfortable."
Stunning Natalie also admits she worries about her appearance, but would never have cosmetic surgery to alter the things she dislikes.
She said: "If I have a pimple I want to get rid of it."
Asked if she would consider going under the knife, she added: "I would hope not."
