Gilbert Arenas might wanna pay attention ... 'cause his baby mama CAN HOOP!!!!
Check out former "Basketball Wives" star Laura Govan BALLIN' OUT at Floyd Mayweather's celeb charity basketball game at Calabasas High School this weekend.
She drains a 3-pointer ... then gets back on defense and gets RIGHT IN FLOYD'S FACE, forcing him to miss his ensuing shot.
Plus, when the action goes back the other way ... Laura boxes out the champ LIKE A BOSS!!!
We'd say Gilbert would be proud ... but, Laura wasn't in a thong.
