Nick Jonas is heading back to Broadway.

The youngest Jo-Bro will join the cast of the Tony Award winning music, How to Succeed in Business Without Really Trying, in January after Glee’s Darren Criss finishes his short run. (Criss took over for Daniel Radcliffe, who starred in the revival when it was first mounted last March).

Jonas, 18, made the announcement on his Twitter account Wednesday, writing, "It's official. I'm coming back to Broadway ... So excited and honored to play the role of J. Pierrepont Finch in 'How to Succeed in Business Without Really Trying' next year!"

Glee’s breakout star Darren Criss will make his Broadway debut when he takes over for Daniel Radcliffe for three weeks in the hit musical How To Succeed In Business Without Really Trying.

The charming chief Warbler on Fox’s smash hit show will replace the Harry Potter star to play J. Pierrepont Finch from January 3 to January 22, with January 1 being Radcliffe’s last show. (It’s not clear if the show will continue after Criss finishes his run).
