Super-group NKOTBSB (New Kids on the Block + Backstreet Boys) have finally released their first joint single -- and it's a song made in boy band heaven!
While the two acts have been touring together since last year, the track, called "Don't Turn Out the Lights," is their first collaborative effort.
NKOTBSB's first album is set to drop May 24 -- and will reportedly feature 5 songs from each band and a collection of joint songs.
