Two members of two of the most successful boybands in HISTORY came together for a duet! The Backstreet Boys' AJ McLean and *NSYNC's Joey Fatone, shared the stage for a fun duet at Joey's 40th birthday party! You would think it would've been an *NSYNC duet, but look at the joy that filled the room when "I Want It That Way" blasted over the speakers!
WE'RE SO UPSET WE WEREN'T THERE!
