I've had a few gigs where things have got out of hand and there has been a huge crush with my fans. They are important and I don't want them being hurt. They are a mad crowd.

Interviewer: "What keeps you grounded?" Bieber: "Gravity." Interviewer: "What's up, Justin?" Bieber: "The sky, man."

I learned if you have $100 or $100 million - if you spend more than you have, you’re going to go broke.

I'm a really claustrophobic person to begin with. I hate elevators, especially crammed elevators. I get really scared. So I think that it's very definitely scary when girls are all around me and I can't go anywhere. At the same time, I guess I got to get used to it, you know what I mean?

I have crushes, but they're all too old. Like Beyonce -she has a husband, I might get shot. I went up to give Beyonce a hug at the Grammys and Jay-Z said, watch out buddy! He was kidding, but you know.

I wear black diamonds instead of regular ones because I’m not flashy, just flossssy.

I was once chillin in my room, watching TV, just in a regular place.. And now I'm in this big world, living my dream and, you know, doing what I love. It's just crazy how it all came around.
