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 are certain nights that you know you hit that crazy note and you know that spin spinned extra fast. And you look out and people are just into it and you've worked so hard and now it's paying off and you can see why you dedicated your life to this.

[on comparisons to J-Lo] It doesn't annoy me, no, because I respect J-Lo. I like her, I think she's great. And I know that I'm over a decade younger than her, it's so flattering that I'm so young and people are comparing me to someone who has accomplished so much. But I don't think I'm like anyone else and really, I'd rather not be compared to anyone else.

[on her song "Bootylicious"] I wrote that because, at the time, I'd gained some weight and the pressure that people put you under, the pressure to be thin, is unbelievable. I was just 18 and you shouldn't be thinking about that. You should be thinking about building up your character and having fun and the song was just telling everyone just forget what people are saying, you're bootylicious. That's all. It's a celebration of curves and a celebration of women's bodies.

Who I am on stage is very, very different to who I am in real life. But I don't see that having a sexy image when you are on stage means that you don't love God. No one knows what I'm really like from that. I like to walk around with bare feet and I don't like to comb my hair. I'm always so glammed up and so diva on stage and that's what they see. People don't understand that... No one knows my personal relationship with God and it's not up to me to prove that to anyone.

For me, it's about the way I carry myself and the way I treat other people. My relationship and how I feel about God and what He does for me, is something deeply personal. It's where I came from, my family, I was brought up in a religious household and that's very important to me. But I understand the mentality of people. I know that people judge others based on certain things. I know how celebrities really are. I've done it too. You meet people - rock stars, rappers, whoever - who you have seen on television and you go into their homes and they are regular people, just like everyone else.
