Nothing has that fire we feel when we're onstage.

'Fast Life' is just about going out with your friends and having a good time - I think it's one of those songs that people can relate with and like.

I went to sleepaway camp seven years in a row. I was such a pro.

Adele's amazing, I think the world of her and her music and I think Tinie Tempah is cool. To work with someone like Kanye West would be awesome.

If it's the first kiss, it's important for the eyes to be closed so you know it's real. It's almost like a Disney movie!

The first time I smoked weed was with Demi [Lovato] and Miley [Cyrus]. I must have been 17 or 18. They kept saying, ‘Try it! Try it!’ so I gave it a shot, and it was all right. I don’t even smoke weed that often anymore.

I'd love to act more. I've had to turn down multiple movies because I was on tour, but it's encouraging to know that someday there might be the right role, the right timing. And I've been writing a lot of music, so hopefully very soon I'll have recorded a project of my own. I also want to get a boat and open a restaurant.
