Jonas Brothers

Jonas Brothers fans were shocked and bummed when they cancelled their tour, citing a "deep rift within the band." While that explanation sounds shady, it may be a euphemism for a bigger problem: Joe Jonas is rumored to be dealing with addiction issues.

Something is rotten in the state of Jonas. Two days before their tour was set to begin in Philly on Oct. 11, the Jonas Brothers have canceled their fall trek. Apparently, the band -- comprised of brothers Kevin, 25, Joe, 24, and Nick, 21 -- are disagreeing majorly over the musical direction of the group.

Happy 21st birthday today (Sept. 16) to Nick Jonas! The youngest Jonas Brother marked the milestone in Las Vegas with family and friends, including girlfriend Olivia Culpo and big brothers Joe and Kevin.

Good news for Jonas Brothers fans! The JoBros are finally finished with their comeback record, and they have a trajectory set for its release: this fall! There were a lot of twists and turns leading up to the record's completion, and some of those came from unexpected influences.

What do you get when you mix a pop sensation, reality TV star and E! Correspondent? Kevin Jonas. The 'Jonas Brothers' have sold over 20 million albums worldwide and most recently celebrated the success of their new single 'Pom Poms' debuting at number one in 16 countries on iTunes.
