I'd like to go the Cher route and act and sing and write and have a TV show and do it all.

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.

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 got called to write for Aerosmith, nothing ever came of it, but I ended up spending the day with Steven Tyler and going to his house and we sat down at the piano, just me and him, and he sang for me and played, then he asked me to sing for him, and then we sang harmony together. That was just a big moment where it was like 'oh my god, my life is crazy!' It was really cool.

Sometimes I write a song and I'm down with it but I'm like yeah, whatever, and then everybody loves it and then it blows up. I'm like: "Okay! I didn't see that coming."

If you can take it to the next level and really tell an interesting story in a unique and fresh way, then I feel like that's a great song.

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.
