‘No Strings Attached’ star Ashton Kutcher has just finished filming some steamy scenes with gorgeous actress Natalie Portman, but he says they were aiming to make them funny rather than sultry. “I find that having sex and intimacy, when it’s great, it’s funny,” explains Ashton, who is married to A-list celeb Demi oMore. “The scenes [in the movie] are sort of meant to be funny or comedic. The real challenge was, you’ve got 50 people looking at you, you’re with someone you don’t really know, and you’re trying to make sure they’re comfortable, you’re trying to be comfortable, and now, you’ve got to be funny.”
