I was writing songs as a kid about leprechauns and Catwoman and teapots - whatever it is that little girls wanna sing about. The first song I wrote was called "Kitten." It was about a boy named Liam, who I was just crazy about.

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.

It's just funny that anybody would care at all to take apart the words that I write. It's kind of cool!

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.

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

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.
