Simon Cowell is tight. That's why he's so successful - he's able to keep his money to himself.

I'd always walk my girlfriend home, i'm too protective!

Katy Perry still gets me every time. She's very funny in person! We met at the Teen Choice Awards and she pulled my cheeks apart and told me how cute I was. My life was literally flashing before my eyes!

I'm quite claustrophobic, and I don't like everyone crowding around and shouting the same questions.

I'd rather be called a boy and play with paper airplanes than be called a man and play with a girl's heart.

I want to sell out arenas and make an album and work with some of the best artists in the world.
