A huge part of youth is how you behave: I'm always looking for fun and anything that makes me feel alive - that in itself keeps me feeling young.

When I was younger, I used to look at movie stars with pencil-thin noses and think about a nose job. I've got a grown-up baby nose; it's not chiseled and structured. Then I saw how beautiful Audrey Tatou was in 'Amelie' and thought, 'She's got a nose like mine, and if she can have a baby nose, so can I.'

I've grown up in the public eye, and every decision I've made has always been so public and often inaccurately reported.

I've been told if you're an actress you can't sing, if you're a dancer you can't act, you can't do theatre and be respected if you've done a TV soap, you can't have a No. 1 record. All these different things they've told me I can't do, but I wanted to do them, so I've done them.

The degree to which society creates wealth, I think, is largely determined by government and financial systems.

A fan sent me a letter and a $10 bill. It's a short letter - all she said was, 'Hey, since it's harder for you to go out these days without getting photographed, here $10 for a pizza.' I was like, 'Aww, she sent me money for a pizza so I could eat at home!'

Channel your heartbreak into work, then use that extra money to treat yourself to a new handbag.

I think some people who have never met me have a misconception that when I was living with my father when he was successful, that I was somehow adversely affected by his success or the money he had and was making at the time.
