It's really liberating and fun to be writing stuff for myself, and really have the freedom to say what I want to say and not really have to think about what somebody else is going to say or have to edit myself to speak from someone else's vision.

Obviously I love writing with Katy [Pery], I feel like we're the same person when we write together. Even though we fight a lot, we fight over every line and we pull each other's hair and we cat-fight all the time, it's always worth it in the end.

I was writing songs as a kid about leprechauns and Catwoman and teapots - whatever it is that little girls wanna sing about.

I tend to get a little quirkier and crazier with my lyrics and come from a different angle when I'm writing for myself.

I like to go to the movies at The Hollywood Forever Cemetery. They do this thing in The Hollywood Forever Cemetery in Hollywood where everybody sits out on the grass and they project movies and it's very romantic and very old-school Hollywood, so I love that.

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.

Ke$ha is super talented and super fun and always down to party - I love that girl.
