Looks like Matthew Morrison just can’t shake his boy band nostalgia. The Glee heartthrob is joining New Kids on the Block and the Backstreet Boys as a special guest on their reunion tour, known as the NKOTBSB Tour.

Morrison, a former member of short-lived boy band LMNT and a Tony Award nominated Broadway veteran, is looking forward to joining the pop-and-dance extravaganza. "This was an opportunity I couldn't pass up," said Morrison. "I am so appreciative of my fans and I'm planning to give them a great show."

Morrison is best known for playing music teacher Will Schuester on Glee, and released his self-titled debut album last week. The album features duets with Sting, Sir Elton John, and Gwyneth Paltrow, who briefly played singing substitute teacher (and Schuester's girlfriend) Holly Holiday on Glee.
