"One relationship that meant a lot to fans was the one I had with Demi Lovato, who I’ve known for years. We had been friends forever, we were both Disney kids, and because we played a couple in the Camp Rock Disney Channel specials—and fans liked seeing us together—we eventually dated for a month. I really got to know her and got to see the ins and outs of what she was struggling with, like drug abuse. I felt like I needed to take care of her, but at the same time I was living a lie, because I wasn’t happy but felt like I had to stay in it for her, because she needed help. I couldn’t express any of that, of course, because I had a brand to protect.
