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.

I've always been able to just concoct a melody quite easily - it's just kind of instinct, really. You've got to channel your subconscious.

I can't wait to get on stage, because there you don't worry about whether you'll ever get married because your life is insane, or whether you'll ever have another boyfriend again, you don't worry about the typical boundaries of how your life has to be.

I want people to get hit and caught by my music.

I'm one of those people that is up for most things. When I was offered to sing at the Oscars I was like, 'Yeah, I want to know what that's like!' I'm always curious to know what things are like - as long as you're not compromising who you are.

I try to maintain a healthy dose of daydreaming, to remain sane.

The release of 'Lungs' was so hard. It was terrifying, because it was the first time doing everything. The first experiences of media exposure were almost paralysing. I spent a lot of time crying on the floor of the studio - it sent me a bit mad.
