Madison already loves being a mom to her adorable daughter. In October, she opened up to Yahoo Parenting about handling the subject of Playboy with the little girl.
"From Day One I've tried to raise her to know she has value, her body parts have value, and she doesn't have to do something cheap or tawdry to get attention," she said. "If she wanted to do — and God forbid she did — I would tell her my whole experience with it and I'd be honest that it wasn't what I thought it would be."
