Diddy Kim, Kanye, Jay, Bey Say HAPPY 50TH BIRTHDAY!!!

Diddy celebrated his half-century on earth in pretty spectacular fashion, with the help of several tons of celebs.

The mogul's 50th birthday bash went down Saturday at his $40 million Holmby Hills home, where Diddy celebrated with Jay-Z, Beyonce, Kim Kardashian, Kanye West, Khloe Kardashian, Kylie Jenner, Dr. Dre, Pharrell Williams, Cardi B, Offset, G-Eazy, Chadwick Boseman, Post Malone, Tyler Perry, Kobe Bryant, Machine Gun Kelly and on and on.

Possibly the biggest headline from the evening, Jay and Ye shaking hands! Seemingly squashing their years-long beef.

As for the performers ... how 'bout Mary J. Blige, Usher, Lil' Kim and Doug E. Fresh?

As for the eats ... McDonald's apple pies, breakfast sandwiches and some fancy stuff too.  There were lots of CBD and weed products served -- courtesy of The BRN Group -- and, of course, Ciroc Vodka all over the place.

Diddy's birthday is actually November 4, but he apparently waited so all his friends could join him.

He's had a rough patch for sure ... a little more than a year ago the mother of his twins -- Kim Porter -- died due to complications from pneumonia.

The cake inscription was short, sweet, and to the point. It simply said "LOVE."

A good time ... clearly had by all.
