I was eating bad stuff. Lots of sugar and carbs, junk food all the time. It makes you very irritated.

I'm famous, so I can't, like, really walk around in malls and stuff like that. I don't really have as much privacy.

I think it's awesome.

On my first album I was wearing a lot of guys pants, baggy clothes and stuff like that. I was 17 and I was a little tomboy. And you would never see me wearing a dress or heels on my first record.

Actually, I know for a fact there are some young female artists who don't even sing on their own records and who don't sing live. And that is pathetic.

It's important to be thankful, even if you're poor. I mean, come on, we all have clean water—well OK, not people in the developing world.

It's easiest to write songs when I'm either really in love or really mad at a guy. It's just always best when I'm feeling superemotional.
