Olympic basketball players' hoop dreams brought out some huge stars to the gold medal match ... and they just saw the U.S.A. eke out victory against France.
Jimmy Fallon led the coterie of famous faces at the event ... grinning big courtside and even stopping to snap some photos with French President Emmanuel Macron.
U.S. Olympians past and present -- like two-time basketball gold medalist Scottie Pippen and track star Sha'Carri Richardson, who's taking home serious hardware from Paris -- shouted from the sidelines too.
