"I read the script and I was like, 'There's no way that sweet Jennifer Aniston is going to say these words and they're going to sound sexual and aggressive,' but then it was like, 'Whoa, she's like a crazy diva sex machine,' " costar Lindsay Sloane said at last night's Hollywood premiere of the movie. "She ad-libbed a lot. Sometimes she would say things and after they would call cut, she would be like, 'I don't know. Isn't that taking it a little too far?' But then everyone loved it."

Story: What does Jennifer Aniston's first tattoo say?

Day, who plays the target of many of Aniston's antics, cracked, "I think there were a couple of times we really had to rein her in. We were like, 'That's too raunchy.'"

Those who know Aniston well aren't that surprised by her dirty side. "That's just like a regular Tuesday for us," said longtime friend Kathy Najimy. "She's so many more things than people think she is. That's definitely in her."
