Leslie Mann: (in 2008) My daughter Maude, who's 10, is in love with [teen actor] Zac Efron. And I just did a movie with him called 17 Again, where he plays a grown man in a 17-year-old's body. He plays my husband. So, we got to kiss, which was very exciting for Maude. When I got home from work after doing the kissing scene, she ran up to me and licked my face because she wanted to taste Zac Efron's spit!
Leslie Mann: I used to go on auditions, not intending to be funny, but people would laugh, and it would throw me. I think there's just something weird about me. I'm just odd. Really, I didn't know who the hell I was for a long time. I'm only now just figuring it out.
Leslie Mann: (about fame and acting) All of this is very nice, but I'm mainly focused on being a mom. I have a little book that I wrote in the fourth grade that said, "I want to be an actress when I grow up, but I'll probably be a bus driver. I love my bus driver." It's funny the way things play out.
Leslie Mann: (in response to her "Knocked Up" co-star Katherine Heigl saying that the movie painted the women as humorless shrews) I don't think I was a humorless shrew. The women were just as funny as the men in that movie. Humorless shrews--who even says that? I just think it's an odd choice of words.
