Are Nick and Demi closer than ever?

Joined by opening acts Little Mix, Fifth Harmony and Cher Lloyd, Demi Lovato's surrounded by a total of ten famous females every night on her Neon Lights Tour. But on opening night in Vancouver, Canada, a surprising guest crashed the girl power party and joined Demi on stage- Nick Jonas! Just before hitting the road, Demi announced that she had appointed Nick (her ex Joe Jonas' younger brother!) as Creative and Musical Director for her worldwide tour. While Demi and Nick have always been close friends, their bond has surely strengthened in the past few months! On opening night, Nick even treated fans to three duets with Demi: "Stop The World," "Catch Me" and "Here We Go Again." Love their close connection!
