Joe Jonas ‘rolling solo’

Joe Jonas and girlfriend Blanda

Joe Jonas “ventured out alone” in Los Angeles amidst rumors of a Jonas Brothers split.

The family boy band cancelled their concert tour on Wednesday after quarreling over the weekend.

It is rumored that the Jonas Brothers, which comprises Nick, 21, Joe, 24, and Kevin, 25, may disband altogether.

TMZ captured Joe “rollin’ solo in L.A.” on Thursday and the middle brother purportedly “hit up SoHo House in West Hollywood [in the] afternoon … sans brothers.”

According to the website Joe “ventured out alone” just days before he and his siblings “are expected to decide the fate of the band this weekend”.

Fans are sad about the prospect of the Jonas Brothers breaking up and many have taken to social media to express their grief.

“Just got my refund email…….. @JonasBrothers do you hear my heart shattering into a million pieces?” @SimSimaJB wrote on Twitter.

The band’s spokesperson Jesse Derris confirmed to People that they were argued over music, not anything personal.

“There is a deep rift within the band,” spokesman Jesse Derris told the magazine. “There was a big a disagreement over their music direction.”

Ticket holders for the cancelled tour will have their money refunded and Derris admitted it “remains to be seen” whether the Jonas Brothers will make new music together in the future.

The brothers, who sold over 20 million albums worldwide so far, have worked on individual projects over the last few years.
