“I change diapers. It’s very humbling, changing diapers, but I’m happy to be doing it. Taking care of the baby is so much fun. I love seeing her grow up. She changes every day.” Action man Bruce Willis enjoys taking a hands-on approach to fatherhood. The actor welcomed his fourth daughter, Mabel – his first with second wife Emma Heming, early last year (12). He also has three grown-up daughters with his ex, Demi Moore.
