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.

I think one day I'd like to win an Oscar.

There's a feeling that you get when you write songs where... it feels like it's destined to do something. Then sometimes you get that feeling with a song and it never goes anywhere, that happens all the time too, so you never really know.

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.

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.
