Lizzo damn near blew the lid off Staples Center when she twerked her butt off.
It all went down Sunday night during a break at the Timberwolves-Lakers game ... while the Laker Girls were performing to the rapper's Grammy-nominated track "Juice," Lizzo got all hyped up ... rapping along before going HAM.
Lizzo -- who was sitting courtside -- was right there on the jumbotron for all to enjoy ... dancing before pulling her t-shirt dress up and putting on a twerk show ... proudly displaying a black thong and fishnet tights.
