My grandmother, whom we call Biel, thinks it's very unbecoming of me not to smile for the paparazzi. So every time I see them, I think, 'Smile for Biel!'

I had my bad-boy moment in my teens. I'll never do that again. It wasn't pleasant, and I learned my lesson. It was sexy and mysterious, and it's like, 'Look how cool they are,' but it's just not worth it. He was lying to me and accusing me of cheating - but then I realized he was the one cheating.

My Barbies were usually naked. Once, I took their heads off, cut their hair, drew on their short, spiky hair with some markers, then stuck the heads on Christmas lights. Every year, we'd string our tree with those Barbie heads. It looked demonic. My parents were so cool - they saw it as a form of self-expression.
