It's very flattering when you look into the crowd and people have made an effort and dressed in your style.

I think an encore is perfectly acceptable, but I find it so weird when people do two or three.

The stage is the place I feel comfortable - it's almost as if real life is where I feel most nervous. Conversations are a lot more nerve-wracking.

I've been having this really weird anxiety dream about arriving too late or too early, and the people in charge are like, 'You have to leave! You have to go back to the hotel and get ready!' And I use the wrong exit, and I'm running down the red carpet in ­pyjamas, like, 'No! Don't look at me!'

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 got quite a vivid imagination and I'm easily overwhelmed by sensations and things that are beautiful or scary. I don't think I've ever seen a ghost - I think I'm probably haunted by my own ghosts than real ones.

Going to parties usually makes me feel depressed, just because I have such social fear after meeting people.
