(Talks about Miley Cyrus 'I always thought I'd be really fun to sing a song with Miley.

My experience with songwriting is usually so confessional, it's so drawn from my own life and my own stories.

Every one of my regrets has produced a song I'm proud of.

When I was a little girl I used to read fairy tales. In fairy tales you meet Prince Charming and he's everything you ever wanted. In fairy tales the bad guy is very easy to spot. The bad guy is always wearing a black cape so you always know who he is. Then you grow up and you realize that Prince Charming is not as easy to find as you thought. You realize the bad guy is not wearing a black cape and he's not easy to spot; he's really funny, and he makes you laugh, and he has perfect hair.

Since I was old enough to understand what a songwriter/producer is, I've had a curiosity about how Max Martin creates what he creates. I wanted to see that happen. I wanted to be there. I wanted to learn from him.

Heartbreak is the national anthem. We sing it proudly.

Through it all nobody gets me like you do.
