Demi co-write this sober soul-searching number with John Mayer. Lovato and Mayer penned two songs together but the second one they wrote, "Shut Up and Love Me" was left off the album for unknown reasons. The teenage pop star told MTV News that she didn't have to work very hard to convince Mayer to work with her, since it was he who made the effort. She explained: "I guess he had heard I was a huge fan, and he sent me a letter. Then we ended up writing together. And it was really great, 'cause he actually reached out to me, and it was like a dream come true." Demi added: "The process of the collaboration was actually really funny, because he's a really, really funny guy, and he talks a lot, so he'll go off on something. I had a great time. He taught me a lot about the business and gave me a lot of advice."
