Pulse Nightclub: The Final Night of Partying


The last moments before Omar Mateen burst into Pulse nightclub were filled with dancing, boozing and a celebrity performance ... as seen in this video TMZ obtained.

This was the scene inside Pulse early Sunday morning, less than 2 hours before the shooting started. As we've reported ... it was Latin night, and in this video it's clear how packed it was. Clubgoers were taking in a dance contest, cheering, and the MC poured booze freely.

"RuPaul's Drag Race" season 4 contestant Kenya Michaels was there too ... performing onstage.

Kenya escaped the club safely, but sadly pointed out her "best friends" were in the front row cheering for her. She says ... "Now all of them are gone."
