The party was at a mega-mansion, and just about everyone was there ... Jay Z,  Gigi Hadid, Joe Jonas, Cara Delevingne, Kendall JennerKourtney Kardashian, Tyrese,  Miguel, Wiz Khalifa, Amber Rose, French Montana, Heidi Klum, Kanye, Luda, The Weeknd, Christina Milian, Vin Diesel, Bobby Brown, Karrueche and Scooter Braun

Witnesses say Kanye got on the mic and wished the rap mogul a "Happy Birthday." Also, Diddy rapped alongside French Montana.

We are told the birthday cake was apple pie...again.
