Over the weekend Kylie Jenner hosted a birthday blowout fit for a king — Tyga’s son, King Cairo, that is. King turned 4 years old in style with not one, but two race-car themed parties! Saturday Blac Chyna threw her son a bday bash, and the very next day Tyga and Kylie put together a lavish celebration at her house.

Not that it’s a competition or anything, but as far guests go, only Kris Kardashian showed up to rep for her brood at Chyna’s affair while Kris along with Kourtney Kardashian, Scott Disick, the Disick Babies, Caitlyn Jenner, North West and Kendall Jenner partied it up on Sunday at Kylie’s.

The second shindig featured Ferrari decorations, a ferris wheel, a racetrack, an inflatable slide, a trampoline, bungee jumping and horseback riding. Oh, and let’s not forget to mention the Diff eyewear party favors guest were gifted.

Take a peek into the King’s epic bash below.

If she didn’t already, it's pretty safe to say Kylie is gunning for stepmom of the year.
