They're arguably the most popular members of their respective boy bands.  Now, Nick Carter of Backstreet Boys and Jordan Knight of New Kids On The Block are teaming up as Nick & Knight to release a new album and go on tour.

BSB and NKOTB have been working together on and off for years now, but this is the first new project to single out just two of the members.

The album by Nick & Knight will arrive September 2, with a supporting tour set to kick off September 15 in Nashville, Tennessee once Backstreet finishes up their summer tour with Avril Lavigne.

There are two scheduled dates at Trocadero in Philadelphia, on October 11 and October 12. Tickets will go on sale Saturday May 3.
