Is it another sign of the JoPocalypse? The Jonas Brothers have deleted the band’s group Twitter account, @jonasbrothers, although all three siblings’ individual accounts remain active.

Coming on the heels of the JoBros’ last-minute decision to cancel their 19-date fall tour, which was to start last Friday, the Twitter ditching is being interpreted by some as another sign that the group might be breaking up.

“They are not getting along at all. It’s uglier than you think,” a music industry source told People on Thursday about Kevin, 25, Joe, 24, and Nick, 21. That after their spokesman last week told Us Weekly, “There is a deep rift within the band. There was a big disagreement over their music direction.”

That said, Joe Jonas, around whom rumours of alleged drug use have swirled, has been spotted recently by TMZ in the company of a noted sober coach.

The trio previously took a break from 2009 to 2012, reuniting late last year for some shows and promising a new, fifth album to be called V. The tour was to have previewed songs from the forthcoming record, according to Pop & Hiss. Their last full-length album release was in 2009, though Nick and Joe have released solo efforts. Kevin and wife Danielle have been working on their E! reality show, Married to Jonas.
