The BIG3 was ON FIRE over the weekend -- with a ton of huge stars hitting the American Airlines Center in Dallas for the BIG3 Ballout ... capped off with a live performance from T.I.
The place was rockin' ... with Ice Cube, LL Cool J, Gary Payton and more showing support for the league's intense 6-game showcase just 1 week before the playoffs begin. The championship game is on Sept. 1 at Staples Center.
The basketball action was solid -- with stars like Tri-State's Amar'e Stoudemire and Aliens' Greg Oden battling it out on the court ... where things got pretty chippy between the 2 big men.
And, with so many players in the league looking to make the jump back to the NBA, it's a pretty big deal to have Dallas Mavericks honcho Mark Cuban sitting in the front row.
By the way, Lisa Leslie's Triplets squad is currently in 1st place -- with stars like Jannero Pargo and Joe Johnson, who just set a BIG3 record for points scored in a season (175).
