The 29-year-old film beauty told the mag she found her solo sex scene in Black Swan 'super awkward' to film.
And she reckons women can have sex without having a relationship, like her character in her new movie, No Strings Attached.
Talking about the infamous scene in Black Swan, she said 'a lot' of people were on set when it was filmed.
'It's super awkward,' she said.
'Anyone who tells you otherwise is not being honest… or they're a little off.'
Asked if she thinks women are capable of no-strings sex, she said, 'I certainly have friends who could deal with that and others who could not.
'It's something I've seen in high-achieving women - they compartmentalize.
'You've got your work, your friends, your exercise, and your sex.
'You can tick off those boxes.'
