When the Jonas Brothers canceled their tour just two days before it was set to kickoff fans were shocked and disappointed, but a new report points the finger at Joe Jonas, claiming the middle brother has a secret drug problem that prevented the band from touring.

Source told STAR: ‘He’s been dealing with substance abuse issues for quite some time. His management team, friends and family have been begging him to seek help. The tour would have never survived with how Joe was behaving.’

Reports in March revealed that a sex tape existed between Joe and girlfriend Blanda Eggenschwiler, but Joe’s rep spilled: ‘There is no truth or validity to the story. It is completely false.’ However, if Joe’s team had looked deeper into the sex tape accusations instead of laughing it off, they may have uncovered his downward spiral.

‘At this point, Nick and Kevin don’t care what is going on with the band, they just want to see their brother healthy. They’ve had discussions with Joe about their fears for him and the importance of getting help.’

Joe has been photographed with drug-addiction specialist, Mike Bayer, who also worked with his ex-girlfriend, Demi Lovato: Everyone is rooting for Joe to get healthy.’
