I'm a happy-go-lucky character. I'm not that miserable. But I can never let anyone into my world.

America is a really delicate flower that needs a lot of attention.

I absolutely loved being famous. It was all great, up until the point when it wasn't.

I've never felt like I had anything important to say.

What's problematic about playing stadiums and driving around in private jets and drinking champagne at 8 o'clock in the morning? What's wrong with that? I haven't got a problem with that. I can't fathom why people would.

If I can give you any advice, it's this: every hour that you spend sat on the couch doing nothing, put it to good use, because when you have kids, an hour is like a lifetime.

If I ever get to go to the moon, I'll probably just stand on the moon and go 'Hmmm, yeah...fair enough...gotta go home now.'
