I like the influence of the macabre, but I don't believe in ghosts.

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.

In terms of influence, my style icons have been a mixture of Julie Andrews and Olivia Newton-John. When I was little I used to watch 'Grease,' 'Mary Poppins' and 'The Sound of Music' a lot. If you put all those things together you do kind of get my outfits. A slightly tarty nanny in a second-hand outfit. That is pretty much what I wear.

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.

But I don't like working on lyrics publicly in the studio - I prefer to take them away and work on them in my bedroom.

There are a lot of people out there who lie about their age and I think it does us all a disservice. It can't all be over when you hit 30. That would be rubbish.

Trust your instincts: they tend to see you right. By listening to them, at least you can sleep at night.
