Everything to know about Diddy's star-studded 50th birthday party

Diddy's 50th birthday party was one for the ages.

The rap mogul celebrated a half century with a star-studded party at his Beverly Hills mansion on Saturday night, with an A-list roster of guests that even the biggest of awards shows couldn't have matched.

On hand to help Sean Combs commemorate his birthday were the likes of Beyoncé, Jay-Z, Kim Kardashian, Kanye West, Kris Jenner, Mary J. Blige, Dr. Dre, Leonardo DiCaprio, Naomi Campbell, Tyler Perry, Usher, The Weeknd, Snoop Dogg, Cardi B, Janelle Monae, Regina King, Kobe Bryant, Kelly Rowland, Kevin Hart, Paris Hilton, Fergie and Pharrell.

While Diddy actually turned 50 back on November 4, insiders told Page Six that he rescheduled the bash three times in order to adequately pay homage to his late ex, Kim Porter, who died last year and would've turned 48 on Sunday.

Sources also told the outlet that invitations to the exclusive soirée came in the form of audio messages recorded by Diddy's longtime friend and fellow icon, Naomi Campbell. "You’re invited to Diddy 50… only come with dancing shoes and good vibes," the invite reportedly said.

The party reportedly started with Ciroc cocktails by the pool before guests were led into a tent where Mary J. Blige delivered a hits-filled surprise performance for over an hour. At one point, Diddy's sons delivered a toast, as did Usher. The night ended with DJ Cassidy spinning hits for hours.

"It was like a superstar convention!" a source told People. "The musical giants of our time were all there to pay their respects."

Perhaps expectedly, most of the juicy details to leak from inside the star-studded event have to do with the Kardashian family: While Kim and ex-boyfriend Ray-J were both there, they reportedly didn't interact, and the same can be said for Kylie Jenner and her longtime ex, Tyga, who was also there.

Kim and Kanye also had a big reunion at the party: They were photographed greeting Beyoncé and Jay-Z, who they reportedly had a falling out from several years ago. According to onlookers, any bad blood appeared to be in the past.

"They greeted each other and seemed friendly and happy to see each other," a source told Us Weekly. "The Carters and the Wests were all in a section behind Diddy and his family."

The day after his 50th birthday party, Diddy took to Instagram to share his thoughts on the night along with a gallery of photos taken by photographer Kaito for Vanity Fair.

"Last night was one of those nights I’ll never forget. But something that sticks out to me is what my young creative @kaito put together with @vanityfair," he wrote. "All I can say is wow!! I’ve watched you grow from just a photographer to someone who captures beautiful art. Looking at these images makes me so proud. Thank you King! #DIDDY50 and thank you."
