I don't use sex to sell records, obviously, but I'd be lying if I said that I don't feel like I have to make an effort to look good when I go out onstage, to wear something pretty.

But now - look, I have to take care of myself. I work out every day. I'm a dancer. I've always been an athlete, and I'm one of those people who start to go crazy if they don't run or do something.

I'd be lying if I said it wasn't fun to go to these nights out, like the opening of a film or something, but I dip in and out of it.

I work hard and I will always work hard. But I feel very lucky with the way that it has all come together.

I am not this big celebrity, but it gets really crazy. You have to go through the nuts of blowing up, in a sense, and then figuring out how to live your life with that.

Now, performing is second nature and I love every second of it. It is a very emotional thing when I can't play a song; maybe I'm hitting on something that I don't want to deal with. All of it is so personal. It is like therapy.
