In a shocking new report, sources claim Joe Jonas has a secret drug problem that prevented The Jonas Brothers from touring.

"He’s been dealing with substance abuse issues for quite some time," an insider told Star. "The tour would shave never survived with how Joe was behaving." 

Joe's rep dismissed the story, saying: "There is no truth or validity to the story. It is completely false."

Last week, The Jonas Brothers announced that they'd decided to cancel their upcoming tour.

"There is a deep rift within the band," their rep said in a statement obtained by EnStars. "There was a big a disagreement over their music direction."

According to reports, an argument between the trio – Nick, Joe, and Kevin – regarding the direction of the band and its music led to the decision to cancel their 19-date tour, just days before the tour was set to kick off.

“They had to resolve their issues about the music and direction of the band,” the source told Hollywood Life. “It’s not a personal fight, it’s about the music. They are brothers, they love each other. Yes, they are still speaking.”

The band was expected to release a fifth studio album, V, later this year. The Jonas Brothers have not commented about the band's future.
