The 18-year-old is set to follow in the footsteps of Daniel Radcliffe and Glee's Darren Criss by starring in How to Succeed In Business Without Really Trying.
Taking to Twitter, the Jonas Brother star said that he will take on the role of window-washer-turned-businessman J. Pierrepont Finch in the show.
But he insisted that it doesn't mean that the Jonas Brothers won't reunite one day.
'The three of us are so thrilled to support each other in our individual projects knowing we'll come back together again one day,' he said.
