Natalie Portman and Mila Kunis talk sex scene at ‘Black Swan’ premiere [VIDEO]

Natalie Portman and Mila Kunis are generating a lot of buzz about their ‘Black Swan’ sex scene, which they say was not easy to shoot.

Portman previously spoke with  V Magazine about the ‘extreme’ scene, saying she has become more open in recent years to baring more than just her soul on film.

Walking the red carpet at the film premiere, the actresses were bombarded with questions about the now infamous scene. When asked whether filming it with a friend made it any easier, Portman said, conversely, it was “more awkward.”  Mila Kunis agreed.  She told reporters, “It’s hard to have a sex scene, period. It doesn’t matter if it’s a friend, a male, a female.  You’re with 100-something crew members, lighting you, repositioning you, there’s no comfort whatsoever.”
