I have the world's worst pregnancies.

I'm waiting for the floor to drop out from under me.

Even though I'm a pop singer, I really have more the life of a country singer.

People are really concerned about my relationship status. When I tell people I'm happy being single, they don't believe me. They say: 'You have to be miserable being alone'.

I love Twitter! At first I made fun of it, because it is very narcissistic, and there's already so much narcissism flowing in this industry, I was like, 'Really, one more?' So I was against it at first. But I really love the idea of the direct connection - there's no middle man muddling it up.

I sing songs that I have lived or I write them because I have lived them. I think the believability factor is key.

My kids are obviously growing up very privileged, but I want them to have a servant's heart. We do community service as a family, and I also call them out on things like getting impatient when they stand in line - because they hardly ever have to. But that's just the reality of what they were born into.
