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.

Right now the tabloids are saying I'm pregnant, and they're naming the baby. It's hilarious. I don't know when I'll want to get married. I never pictured myself as a bride, but after my sister's wedding,I did start thinking about what kind of wedding I'd want. I don't think I want a big one.

With a lot of success comes a lot of negativity.

Power is not given to you. You have to take it.

When I hear a great new record, especially when it's by someone that I respect and admire, then a part of me is like, Why didn't I think of that? Why didn't I write that record? It makes you sick, but in a way it can be a great thing. It makes you want to go back to the lab and start writing again. Maybe it will inspire you to try a little harder.

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.

If I weren't performing, I'd be a beauty editor or a therapist. I love creativity, but I also love to help others. My mother was a hairstylist, and they listen to everyone's problems - like a beauty therapist!
