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.

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

I had an epiphany where I realised that there are song titles everywhere - in advertising, in conversations with people at the grocery store - and every time I open my mind to that and find titles, I then weave a story around that.

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.

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

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 love really kitschy bad movies. Showgirls is one of my favorites. I saw House of Versace and died. I'm a big fan of made-for-TV movies because those are instant classics, naturally.
