On Saturday night, Sean "Diddy" Combs celebrated his 50th birthday with a star-studded bash at his Los Angeles mansion in Holmby Hills. The lavish party included a huge guestlist featuring everyone from JAY-Z, Beyoncé, and Post Malone, to Kanye West and Kim Kardashian. There were live performances and, naturally, a whole lot of Diddy-endorsed Cîroc vodka.

Diddy actually turned 50 on November 4 but he decided to postpone the party so all of his celebrity guests could make it. He also used the event as an opportunity to celebrate his late partner Kim Porter, who would have turned 49 on December 15. Porter tragically passed away last year following a battle with lobar pneumonia.

Find out how Diddy celebrated the big 5-0 below.

Who was on the guestlist?

Diddy's invite list read like a who's who of the biggest names in the music industry right now. Guests included JAY-Z, Beyoncé, Kanye West, Kim Kardashian-West, Khloe Kardashian, Naomi Campbell, Dr. Dre, Pharrell Williams, Kylie Jenner, Cardi B, Offset, Quavo, Snoop Dogg, Swizz Beatz, Post Malone, Leonardo DiCaprio, and many more.

JAY Z & Kanye West had a surprise reunion

Perhaps one of the highlights of the party, though, was a surprise reunion between Kanye West and JAY-Z. The two were seen greeting each other and taking pictures together, potentially putting an end to the feuding rumors that have been circulating for the past few years.

Lil' Kim and Mary J. Blige performed

The birthday bash included live performances from Lil' Kim, who performed songs like "It's All About the Benjamins," as well as Mary J Blige, who sang "I Can Love You." Usher and Doug E. Fresh also performed.

JAY-Z wasn't happy with people recording

In the video above, Beyoncé, Saweetie, and Kelly Rowland can be seen jamming to Bobby Brown's "Every Little Step." However, as soon as someone starts recording the moment on their phone, JAY-Z steps in to snatch it away, giving us a little insight into how he and Bey manage to maintain their private life.

Leonardo DiCaprio pulled some interesting shapes

What was on the menu?

According to TMZ, Diddy's guests weren't just served gourmet meals, but they ate McDonald's breakfast sandwiches and apple pies. Cîroc, the French vodka brand Diddy has shares in, was flowing all night, and guests were also offered a range of marijuana-infused products, too.

What gifts he received

Though it seems like Diddy didn't actually receive any presents at the function, his son Christian Combs gave him a lavish present on the day of his actual birthday. The extravagant gift consisted of a diamond-encrusted painting of Diddy, made from 100,000 stones.

According to E-News, Diddy's birthday cake spelled out "LOVE," with each letter frosted in white and adorned with gold candles.
