The bevy of stars hit up the Microsoft Theater in L.A. to pose for photos in their fancy getups before heading inside to enjoy the show.

Major attendees included Ice Spice, T.I., Quavo, Offset, Busta Rhymes, Yo Gotti, Master P, Latto, Chrisean Rock, Angela Simmons, Moneybagg Yo, YTB Fatt, Sexyy Red and Brooklyn Nikole.

Behind the scenes ... the hip hop greats were yukking it up and partying their butts off, which we're sure lasted long into the night around town.

During the awards ceremony, there were a few surprises -- one of which came when the two surviving members of Migos -- Quavo and Offset -- paid tribute to their slain bandmate, Takeoff.

Another memorable moment was when Busta teared up while giving an acceptance speech after receiving a lifetime achievement award.

Then there was Patti LaBelle, who initially botched her tribute to the late singer Tina Turner, forgetting the words to Tina's smash hit, "The Best." But Patti made a quick recovery and ended her performance on a high note.

All in all ... it was a fabulous night with terrific music.
