EXCLUSIVE: Leslie Mann and Judd Apatow's kids have cavities: 'I'm a bad mother.'

Hollywood's hottest comedic actress, Leslie Mann, hosted the Lacoste and Vogue 2009 Pink Croc collection Monday night to benefit the Breast Cancer Research Foundation.

And her costar was her Time "Man of the Year" and Hollywood powerhouse husband, Judd Apatow.

But still at home with the baby sitter were their two daughters, Iris and Maude, who have already appeared with Mommy in Apatow's hit comedies "Knocked Up" and "Funny People."

Are the Apatows becoming like the movie version of the Osmonds or the Cyruses?

Sounds like it. Apatow confesses, "We have a great time when we're working together -- it just may be when we get along best. We don't leave our work on the set. We bring it back to the house, then to the set again." 

Do their daughters want to be the new Miley Cyrus? 

Mann laughed and admitted, "My kids are really smart and have a lot of cavities, I found out today. Which means I'm a bad mother. My older daughter, Maude, who's 11, she's really into school and she doesn't seem to care too much what Miley Cyrus does at all. She's really grounded."

But their life is not as sane and balanced as it sounds. 

"I was sitting in the kitchen tonight, trying to get ready for this, and my kids were screaming and going crazy," Mann admitted. "Every time I try to do two things -- work and be a mother -- it's insane. I don't deal with it well. I don't think anybody can. It's impossible to do, although I'm forever trying."
