Why are the Jonas Brothers doing Camp Rock 3? It is not entirely for financial reasons despite speculation! Joe Jonas made that clear! If you don't know, Joe, Kevin, and Nick are all reprising their roles as Connect 3 band members Shane, Jason, and Nate Gray, respectively, in the upcoming Disney movie. They are also serving as executive producers alongside Demi Lovato, who starred in the first two movies as Mitchie Torres with them. It is unknown if she will reprise her role, FYI. But fingers crossed.
