Diddy hit his 53rd birthday in true Diddy fashion Friday night … Big Party!! BIGGEST NAMES!! Lots of liquor!! And lots of dancing!! The legendary rap mogul threw his lavish B’Day bash at his LA mansion … and the stars mostly came out dressed to the nines to enjoy all the fun. Travis Scott, in a dapper black suit, showed Diddy some love, hugging him as they chatted excitedly. The icons also slammed their fists on a table before everyone sang Happy Birthday to Diddy. Jay-Z was also there but decided to go a little more casual in blue sweats with a matching blue hat. Jay proposed to Diddy with Mary J. Blige, raising their glasses and downing the drink. Other famous attendees … Chris Brown, French Montana, MGK, Teyana Taylor, Kehlani, Tinashe and Jermaine Dupri. Of course, Diddy got presents and several cakes with the word “Love” written on them. To top things off, attendees climbed onto a giant mattress in the backyard and danced their butts off … to Diddy!! Didi’s new business partner, Elon Musk, was absent from the festivities. As we reported, Didi invested more than $10 million to help Musk buy Twitter. But we’re sure Diddy gave Elon a pass for missing his soiree… after all, Musk is dealing with a lot of drama at his new social media company.
