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

As long as I can reach somebody, then I feel like I'm doing my job.

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.

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

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.

A lot of people, Lady Gaga and Katy Perry and a lot of people have written for other people, and of course Bruno Mars. So I think it's a great way to break into the industry and show people what you can do and show them your talent and people tend to listen a little differently to your own music as an artist, when you've proven yourself as a good songwriter for other artists.

I've been close friends with Katy since teenagers, before she was Katy Perry. She's always been a great resource for me to pull from and watch - from her choice of how public she wants to be about her personal life on down. I also watched her develop from the coffee-house singer-songwriter I knew to her be to playing arenas and killing it.
