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

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

I love writing with Adam Lambert. He's really funny and very fun, he's a great friend.

Maybe I'd like to be a little more than friends with Ryan Gosling, but I'd just like to hang out occasionally.

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."

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.
