Blac Chyna Throws King Cairo Gamer Birthday Bash

Blac Chyna and Tyga are at odds over custody of their son King Cairo — a battle that was pretty obvious from the guest list for King’s 11th birthday bash!!!

TMZ Hip Hop obtained footage from inside the event which went down Sunday in L.A. … it was a private party, strictly for close family and friends. Not shockingly, that did NOT include Tyga.

While King’s pops wasn’t there, we’re told roughly 25-30 kids turned out to help KC celebrate … and Chyna — or Angela White as she’s now known — belted out the birthday song, complete with the MLK remix.

Chyna’s mom Tokyo Toni was also there cutting a rug as the whole party jammed to a Bluefacetrack!!!

Sources inside the shindig tell us it was produced by Royal Game Bus, who kept the kiddos busy all afternoon … providing them with Oculus Quests, a cotton candy machine, candy bags and all the games they could play.

It’s obvious the kids all had a great time, but the same can’t be said for King’s parents.

TMZ Hip Hop obtained court docs from the latest court boutbetween Tyga and Angela … she’s petitioning for equal joint custody, but he’s not backing down.
