London: The Oscar winning star Natalie Portman said doing lesbian love scenes with  Mila Kunis in 'Black Swan' was really awkward.

Natalie who won an Oscar for playing Nina, a tortured ballerina in the Darren Aronofsky-directed movie, says it was uncomforting to shoot the scene.

“It's super awkward. Anyone who tells you otherwise is not being honest. or they're a little off," said Natalie Portman who is expecting a baby with her fiancé Benjamin Millipied.

Portman, also had some saucy scenes with Ashton Kutcher in comedy 'No Strings Attached' and acknowledges that casual sex is a frequent modern-day occurrence.

"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 compartmentalise," Natalie said about her role in the movie.
