Oscar-nominated actress Natalie Portman is known for dramatic roles, like her intense, Golden Globe-winning turn as a prima ballerina in 'Black Swan.'

But as seen in 'No Strings Attached,' out this Friday, the talented beauty also knows how to play it up for laughs. In Ivan Reitman's comedy, Portman is Emma, a doctor looking for sex (and nothing else) from pal Adam (Ashton Kutcher).

It's a role that required her to really let loose in more than just a couple scenes. Not that she found it hard to let her freak flag fly. "I'm pretty freaky," she laughs. "Making a fool of yourself, for me, is relatively easy. Natural, I would say."

Ashton Kutcher, Portman's co-star, says that the movie's idea of friends with benefits may work for both parties initially, "eventually a relationship sort of comes to that cliff, where you either have to jump full in, or you have to go back the other way," Kutcher says.
