Bronny James put on a show for a star-studded crowd at Overtime Elite's opening night on Thursday ... hitting four 3-pointers on a 16-point night in front of Quavo and Swae Lee!!
"OTE" -- a pro basketball league for 16-19-year-olds -- held an exhibition in Atlanta ... with Bronny's California Basketball Club going up against City Reapers.
The celebs picked a good game to get a glimpse of Bronny -- because the Sierra Canyon point guard made it rain from behind the arc several times.
Paolo Banchero, Jalen Suggs, Druski, K Camp, Atlanta Mayor Andre Dickens, and Mike WiLL Made-It were also in the building to witness Bronny's outing.
