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 had an epiphany where I realised that there are song titles everywhere - in advertising, in conversations with people at the grocery store - and every time I open my mind to that and find titles, I then weave a story around that.

I think I've learnt a lot about bullying and how to deal with bullying and how to get over that and to just be yourself and forget the haters.

Every time I work with Dr. Luke I learn something new. He's kind of like the Andy Warhol of pop music, where he mass produces his art but it always still has heart and always still has an emotional thread to it. I think he's really a genius and I'm so lucky to have gotten to work with him.

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 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.

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.
