Ashton Kutcher may be turning 30 tomorrow, but he's never too old to beat up on his wife's ex-husband Bruce Willis. Of course, it's just play fighting and the two men are really seriously good friends. Food for thought though, who would even win in a fight? Even being 22 years Ashton's senior, Bruce is pretty burly. The whole family — Demi, Ashton, Bruce, the girls — all went out for a little pre-birthday lunch in LA this week showing off just how buddy-buddy dad and step-dad are. While I'm especially excited to see Ashton back on the big screen with Cameron in What Happens In Vegas, his family man side is about as endearing as it gets.
