Cruise and Box have a huge bet riding on who wins the NBA Finals this year: The Golden State Warriors or my Cleveland Cavaliers.  But I'm wondering who gets to claim Bieber for their team?

TMZ obtained Snap Chat video of JB throwing down with a guy much larger than he was outside his hotel in Downtown Cleveland after the Cavs blew out the Warriors 120-90 on Wednesday night.  No one knows what caused the fight, but Biebs was wearing Cavs gear.  Maybe just a little post game smack talk? Feel free to watch it go down below.
