When I write for myself, I just get to be myself.

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.

I am a little crazy but when I'm on-stage, then I really get to play it up and perform and be over the top and it's like an outlet. It's fun to 'wild' out.

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.

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.

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.

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