As hard as it might be to believe, the Jonas Brothers can be separated from each other. For the proof, watch American Idol‘s upcoming season.

Although he previously visited the program as a member of his trio, Joe Jonas will be making a return to the FOX series as a solo act. The boy bander is now the latest musician to serve as a guest judge on Idol.

Jonas’ stint in Dallas will follow the appearances of both Victoria Beckham and Mary J. Blige. Other celebrities on tap include Katy Perry and country singer Shania Twain. Although a Kelly Clarkson cameo had been rumored, a source tells Us Weekly that the Season 1 winner will not be participating.

Season 9 of American Idol premieres in January.
