Chris Paul -- Schmoozin' with Huge Stars ... Before Clips Game

When you play pro ball in L.A., schmoozin' with the celebrities is part of the job ... just ask Chris Paul who chummed it up with Floyd Mayweather and Kevin Hart before Monday's game.

Both Floyd and Kev had courtside seats to watch the Clippers take on the Phoenix Suns -- and each star got a personal visit from CP3 before tip off ... pretty cool, right?

BTW, Kev took his son to the game ... and judging by the look on his face as the Clips pulled away ... dude had a good time.
