Sunday night saw one of the most monumental hip-hop concerts in recent history, and no one knew it was coming.
As guests arrived to celebrate DJ Khaled's birthday at LIV Miami at the Fontainebleau, they found themselves in the company of hip-hop icons Diddy
, Kanye West
, Fat Joe
, Lil Wayne
and Busta Rhymes. Also joining the fun: Kourtney Kardashian
's longtime love Scott Disick
– who was in town filming Kourtney & Kim Take Miami
While some had heard rumblings of Diddy and company's attendance, no one expected what the night turned into – an impromptu concert!
"It was the craziest thing ever," says a source. "Maybe you've seen one or two of these guys perform, but never singing each other's songs together – it was amazing!"
Kanye, enjoying a boys' night out in a black leather T-shirt, received the most enthusiastic response of all when he hopped on stage with Fat Joe and performed his hit "Jesus Walks." The group wasn't taking the party lightly and ordered around 30 bottles of Ciroc Vodka.
Disick, who may seem the unlikeliest piece of the puzzle, apparently held his own with the rowdy group. "Scott surprisingly fit in really well; he seemed totally natural with the guys … you wouldn't have expected it," says one partygoer.
