Kelly: Probably my favorite track on the whole album, just because it's the sexiest song I've ever written in my life, is "Addicted." I love it. Everyone's been there — I wrote this song about someone that you loved but it was almost a little bit like an obsession. You were just like, "I don't really love them," but you were just obsessed with them 'cause you had nothing else to do. Everybody does that at one point in your life. It's totally about that. It's like their drug, it's like you can't get away from them.
