I love really kitschy bad movies. Showgirls is one of my favorites. I saw House of Versace and died. I'm a big fan of made-for-TV movies because those are instant classics, naturally.

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.

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.

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 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.

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.
