But I don't know what guys I like because I haven't been out with enough to know. I'm still learning.

I wanted to sell a million records, and I sold a million records. I wanted to go platinum; I went platinum. I've been working nonstop since I was 15. I don't even know how to chill out.

There's plenty of days when I'm like 'Oh God, why?' But that's just life. It's every job, not just mine. Every moment is not perfect. But it's definitely more good times than bad. You can't even compare. And when I'm on stage it feels incredible.

There's my personal life, my sensitive side, and then me as a performer, sexy and energised and fun.

I have so much admiration for women who are mothers, who balance family and work.

I always treat myself to one meal on Sundays when I can have whatever I want. Usually it's pizza, which is my favorite indulgence.

I think it's healthy for a person to be nervous. It means you care - that you work hard and want to give a great performance. You just have to channel that nervous energy into the show.
