What luxury would I take to a desert island? A mirror. It's true. I'd miss me.

Thank God kids love following an artist. When you get a group who pop, it's the best thing in the world.

You have an advantage if you win. I always think it's best to be remembered as a winner rather than as the runner-up. It's definitely more fun getting the gold than it is the silver.

Anything I shouldn't laugh at makes me laugh. I mean, I'm bad at that, when somebody is singing something terribly and I'm thinking to myself, 'If I laugh now, this is the absolute worst thing I could ever do,' and then I start laughing and I can't stop.

I genuinely believed no one would want to marry me. I am difficult to live with. I'm selfish, quite weird and I need time on my own to think - and then I work all night long. That is difficult for someone to deal with. And it would drive me mad - I could never be my own girlfriend!

Sincerity is romantic. I don't think you need gestures.

You have to be original. The people creating a buzz on YouTube are taking risks, and they're doing something different. I like it when 15 year-olds come on and tell me what to do rather than the other way around.
