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 want my music to sound like throwing yourself out of a tree, or off a tall building, or as if you’re being sucked down into the ocean and you can’t breathe… It’s something overwhelming and all-encompassing that fills you up, and you’re either going to explode with it, or you’re just going to disappear.

I think I've always looked older than I am. I hope that's going to work in my favor when I get older.

When something really hits me, it makes me want to either jump off something really high or lie down and be buried. 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.

For someone so conflicted, who am I to give advice to anybody? It’s such a funny, grandiose idea

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.
