Human beings love poetry. They don't even know it sometimes... whether they're the songs of Bono, or the songs of Justin Bieber... they're listening to poetry.

I had to give Justin Bieber a lot of shirts - he's a friend of the team, and we got a lot of love for Justin Bieber. I like the apparel business. That's another $100 million per year, easy.

It has been wild, you know? I started out just putting a song that I made out on the Internet without being sure if anyone was going to like it, and it took me on tour around the world with Justin Bieber. It's been amazing!

I'd like to work with Justin Bieber. He's talented and he's so young. I know what he's going through. I've lived what he's living through right now. Working with him would complete a circle of sorts for me. And he might find it a worthwhile experience himself.

I'm not a movie star. People know me but they don't necessarily know what they know me for. I get recognised but it's not like Justin Bieber. It's a nice thing people are cool.
