Jonas Brothers 'not getting along'

The Jonas Brothers' rift is reportedly getting "uglier" by the minute.

The boy band cancelled their concert tour last week and their spokesperson confirmed they suffered "creative differences".

It is rumoured the pop trio, comprised of Nick, 21, Joe, 24, and Kevin, 25, are on the verge of splitting up.

"They are not getting along at all. It's uglier than you think," a music industry source told People magazine.

"They are each looking into solo projects. Nick and the Administration are working on another album. They are moving forward away from the Jonas Brothers. I think this is the beginning of the end."

The Jonas Brothers' official Twitter account was deactivated, fuelling speculation that the band is no longer together.

But supposedly the sibling performers remain on good terms despite their professional disagreements.

"The idea that this is acrimonious is wrong," the insider said. "The guys are all talking and haven't stopped talking ever."

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

"I can't read any article about the Jonas Brothers. I'm heartbroken. #fangirlproblems," @diana_saravia shared on Twitter.

The band's spokesperson Jesse Derris admitted it "remains to be seen" whether the Jonas Brothers will make new music together in the future.
