VIDEO : Nick Jonas Opens Up About Friend Demi Lovato's Haunting Past

Coming up in a boy band, the Jonas Brothers, Nick Jonas probably didn't have to deal with much adversity. But being friends with Demi Lovato? That's a different story. Lovato had a meltdown of sorts a few years back, and dealt with everything from depression, to drugs, and even an eating disorder. In speaking with Entertainment weekly, of which he graces the June cover, Nick opened up about being Demi's friend, and going through such terrible things with her. He said "It?s been years of working on herself and getting better, but she?s amazing?and a better singer, too, because she?s healthy. But I was genuinely concerned that I might lose my friend."
