It really does make you feel old. With Bieber, I consider him a friend as we’ve done shows together, but then sometimes I can’t help but feel like his dad. I’m like: ‘Da**, I’m ten years older than you. You were, like, five when I had my first girlfriend.’ It’s just crazy. But it’s good to start young so you can hone your skills, then when you’re older you’ll have this game locked down. I’ve talked to Justin Bieber about this and I’m like: ‘Get in the gym now, practice the skill of the gym, you’ll be buff.’
