I wanted to be a witch when I was a kid. I was obsessed with witchcraft. At school, me and my two friends had these spell books; I always wanted a more magical reality. I had a little shrine at home and I did a spell to try and make the boy in the other class fall in love with me.

Music to me is so internal. It's physical and it's emotional. Whereas fashion is so much about the external that it's almost like a break. It's not inner turmoil. It's total escapism.

All the words are already there when you're singing onstage, it's fantastic. You can lose yourself in what you've created. You're controlling this freedom.

I've just never been a tracksuit-wearer.

I got to live out my 11-year-old fantasies - I got to go on stage with Green Day. Billie Joe called my name from the stage. 'Dookie' was the first album I ever bought. I covered the whole of 'Nimrod' and he'd heard it. That was like the 11-year-old girl dreamed.

When you're dressed up as David Bowie, with your eyebrows completely bleached, and you're doing this kind of strange dance with Paul McCartney while singing "Rebel Rebel" in the middle of the Met ball, and Madonna's looking at you . . . I was just thinking, It's become a bit weird.

The only music I was listening to for ages was old soul. So I wasn't listening to a lot of new music - especially indie music.
