No matter what, I always have expensive designer shoes. It's all about the shoes for me.

In my head, I wanted to be Madonna, but the music I was writing on paper was not what you'd choreograph dancers in costumes to. It was more coffee-house stuff.

Every time I work with Dr. Luke I learn something new. He's kind of like the Andy Warhol of pop music, where he mass produces his art but it always still has heart and always still has an emotional thread to it. I think he's really a genius and I'm so lucky to have gotten to work with him.

I got called to write for Aerosmith, nothing ever came of it, but I ended up spending the day with Steven Tyler and going to his house and we sat down at the piano, just me and him, and he sang for me and played, then he asked me to sing for him, and then we sang harmony together. That was just a big moment where it was like 'oh my god, my life is crazy!' It was really cool.

I was writing songs as a kid about leprechauns and Catwoman and teapots - whatever it is that little girls wanna sing about. The first song I wrote was called "Kitten." It was about a boy named Liam, who I was just crazy about.

I have a reoccurring dream that I'm in the ocean in New Zealand and everything is completely upside down, because it's on the other side of the planet.

It's nice to really have the freedom to write what I want.
