Lil Wayne can't lose when he's got LeBron James on his team -- even when he's squaring off with Birdman.
Wayne got a bunch of Cash Money artists --technically Birdman's artists -- to flock to his NBA All-Star weekend shindig Saturday in New Orleans to celebrate Cash Money Records' 20th anniversary ... leaving Birdman's party relatively empty.
Weezy even reunited with Juvenille, B.G. and Turk for a Hot Boys performance ... intro'd by LeBron.
Other celeb guests included DJ Khaled, Meek Mill, 2 Chainz, 21 Savage and (almost) Future -- who got bounced for bringing more thanb 30 people to the joint when it was already at full capacity.
