I've got quite a curvy shape so I try to wear stuff that's tailored.

I don't think anyone doubts my motives, really. I do what I do and it's not very complicated. Of course, you might hate the music that I make, but I don't think people feel threatened by me just getting on with what I'm up to.

There's so many singers, you watch them and a lot of it is waving around. You don't get this feeling that they're really thinking about what they're saying.

I don't know why people think I'm polished - I often leave the house with buttons missing and ladders in my tights.

Having a successful first album is one thing, but a successful third is another.

I love getting dressed up. Being a pop star is the most brilliant job for that. A lot of girls love shopping, but they might see the most amazing outfit and think, 'When am I going to wear that?', so it's my duty to exploit the fact I do have events I can wear these things to.

I don't think that old-fashioned idea of record companies exists any more.
