Boyz II Men's Shawn Stockman knows the score when it comes to battling the Backstreet Boys on the Vegas Strip ... and they're trailing big.
We caught up with the singer at LAX and asked him if there's gonna be a battle now that one of the best-selling boy bands in history landed their own Vegas residency. Remember, the Boyz already have a hit show there ... which runs through 2018.
So, is Shawn worried about a little comp? Check out the vid ... game clearly recognizes game.
