Living alone, you can do so many fantastic things I've learned. You can like, walk around and have so many conversations with yourself and sing your thoughts. I think I'm the only one that does that.

I heard that when Christina Aguilera went back to her prom, people, like, booed her. I can't imagine going through that. If you know that's going to happen, why put yourself in that situation? I'd rather play for 20,000 screaming people, you know?

Sometimes the lines in a song are lines you wish you could text-message somebody in real life.

I never give advice unless someone asks me for it. One thing I've learned, and possibly the only advice I have to give, is to not be that person giving out unsolicited advice based on your own personal experience.

For me, when I picture the person I want to end up with, I don't think about what their career is, or what they look like. I picture the feeling I get when I'm with them.

I do write nice songs about the guys who are nice to me! Eventually, I'm sure one of them will write a response - that's a pretty scary concept, actually! But I make sure I only write bad songs about the ones who deserve it.

I think that as you grow up, as you get older, we can't get bitter, we can't get jaded.
