while being the perfect entertainer at home with wife Mariah Carey
WHAT KIND OF HOST WILL YOU BE? I come from the world of improv, so expect more humor. I'm bringing out the cool, sexy, corny and goofy side of me.
HOW ARE YOUR HOSTING SKILLS AT HOME? At our dinner parties, I'm always the loudest person in the room, making toasts and making sure everyone is settled. When we had our one-year anniversary in Las Vegas, I got the room together to gather our hands and say a prayer. My wife appreciates that quality in me.
WHEN YOU HAVE KIDS, WILL THEY BE IN SHOWBIZ? I'm not going to be one of those stage daddies who says, "Get out there and sing!" I want to raise some doctors and astronauts. Or even singing doctors!
