As a mother, the one thing that always goes through your head is, You're never enough. You never can be enough - or do enough - for your kids. It's a never-ending issue for me. I had to learn: Don't beat yourself up so much.... You have to take it one day at a time, do the best that you can and enjoy yourself. I notice that if there are some times I've been stressed, because I'm human and stress about things, that affects your kids. So you have to make sure you're a happy mom so they can be happy.

I like meeting all my fans and signing autographs, although it can all get a bit crazy. Yesterday, for example, a boy just came over and planted a big kiss on my face! I was like, 'Hello?'

I think it's important to set up that boundary of respect for your kids at a young age, so they will know, I better listen to Mommy.

Anyone can sit down and write some boring artistic song. Pop music is the hardest [stuff] to write.

I performed at Mom and Dad's party when I was four. Oh my gosh, I was singing a Madonna song, and I peed myself!

I think I'm still clean living. That's - I mean I don't go home and have orgies or anything like that. I'm still the same person I've always been.

Sundance is weird. The movies are weird - you actually have to think about them when you watch them.
