Kevin Jonas reportedly doesn’t want Joe Jonas dating Demi Lovato. Kevin Jonas, the oldest member of the Jonas Brothers, may have just gotten married, but it’s rumored that he has been discouraging his younger brother Joe Jonas from dating his Camp Rock costar Demi Lovato because he doesn’t trust her. Demi, Joe, and Kevin’s Camp Rock 2: The Final Jam will premiere on Disney Channel sometime this year.

“Plain and simple, Kevin [Jonas] doesn’t trust Demi,” a source said. “He’s been telling Joe to have his wits about her and her friends since word got out about their romance.

“He thinks they are perfect on-screen for each other [in Camp Rock] and amazing friends, but that it shouldn’t go any further. Demi has been trying hard to win back everyone’s trust.” — via Showbiz Spy
