If there's anyone who treats Justin like a regular kid, it's his mom. Just last week Justin was grounded, he says. "My mom takes things that I really like, like my computer, my phone," he says. "She takes my phone away for a couple of days and I'm like, 'Oh, I need that!'"

"You can't say, 'Mom, I can't get grounded—I'm Justin Bieber'?" Oprah asks.

"She'll slap me in the face!"
