Happy birthday, King Cairo! Kylie Jenner celebrated her boyfriend Tyga’s son’s 4th birthday with the Kardashian-Jenner family at an extravagant party on Sunday, October 16, just one day after King’s mom Blac Chyna held a similar celebration.

The makeup maven, 19, and her rapper beau, 26, were joined by Kylie’s sisters Kendall Jenner and Kourtney Kardashian, Scott Disick and his three kids with Kourtney, as well as Kim Kardashian’s daughter, North West, and Kris and Caitlyn Jenner.

King’s epic birthday celebration was filled with Ferrari and race-car decorations, notably the same theme as the party mom Chyna, 28, threw on Saturday, October 15.

In one clip, the teen reality star rode the Ferris wheel with King and Tyga, who was overheard asking the birthday boy, “Are you scared?”.

Later, Kylie posted three photos she took with the “Rack City” rapper in a photo booth, kissing him on the cheek and posing with a “Happy Birthday King” sign.

A day earlier, King’s mom, Chyna, who is now engaged and expecting a child with Rob Kardashian, celebrated her son’s birthday with a Lego Ferrari party.
