On stage, you can use your emotions. It's the place where you can channel them. They have a purpose.

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.

I think I should get a bigger between-the-song persona, so then I'm not wandering around the stage like some mad old auntie that's saying hello to people and falling over.

I'm a light sleeper. I've never been one of those people who can put their head down and suddenly everything disappears. Nighttime is the time I get most scared, anxious or worried. In those darker moments before waking or sleeping is when I feel most, I don't know, I can turn on myself, and my imagination can take me dark places.

I quite like the drama of an encore. I think an encore is for those artists who are inclined to do dramatic gestures, and I certainly would say I am inclined towards them.

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.

I'm completely in love with the world but also terrified of it. It creates some overwhelming feelings. Wanting to battle out that joy and fear is part of my music.
