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.”
