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 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.

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

No matter what, I always have expensive designer shoes. It's all about the shoes for me.

I'm a really visual artist, and I love writing treatments for music videos, photo shoots, fashion, and all the visual parts that go along with making an album.

I just want to give people something to dance to, and something to cry to, and laugh to and fall in love to.

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.
