Cheating is bad. That's a big mistake I've made, and I've really hurt people. I've never lied about it, though. I've always been honest.

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.

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."

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

It's really liberating and fun to be writing stuff for myself, and really have the freedom to say what I want to say and not really have to think about what somebody else is going to say or have to edit myself to speak from someone else's vision.

When I write for myself, I just get to be myself.

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.
