Khloe Kardashian went all out to celebrate her daughter’s fourth birthday and held a lavish cat-themed party at their $37 million mansion in Hidden Hills. The reality star spared no expense for True Thompson's big day, and the bash featured a braiding station, giant balloon arches, and custom M&M’s with True’s face on them.

True isn't officially turning 4 until Tuesday, but Khloe and the rest of the Kardashian-Jenner clan came together to celebrate over the weekend.

Khlo took to Instagram to show off the stunning soirée, revealing a massive display arch of pastel-colored balloons that draped the entrance of her $37 million estate. The display, which dwarfed the soon-to-be four-year-old, extended to the backyard. The sprawling backyard included giant cartoon cat cutouts and pink heart floaties in the pool.

Khloe followed True around as she enjoyed a lap of luxury on her big day. There was a massive inflatable pink slide, a trampoline, a face painting station, and even a ball pit stuffed with animals and prizes. The bash also featured a performer dressed as a Squishmallow cat and customized Squishmallow party favors.

Of course, the feline fiesta wouldn’t be complete without real kittens, and in the clips, True is playing with several kittens brought in for the event.

There were plenty of famous faces in attendance. Kylie Jenner and Kim Kardashian stopped by with True's cousins, including Dream Kardashian, Penelope Disick, North West, and Chicago West.

The event took place at Khloe’s new $37 million estate, located next door to mom Kris Jenner’s $20 million plot. The reality star recently opened up about the pitfalls of living next to her famous mother on Jimmy Kimmel Live! Khlo revealed that her mom has some pretty bizarre habits when it comes to her dog.

The massive homes sit in an exclusive gated community in the Hidden Hills area of Los Angeles. The neighborhood is home to plenty of A-list celebrities, and also some family members as well. Kim Kardashian has a $60 million compound nearby, and Kylie Jenner’s pad is just a short drive away.

Khloe has created a fortune valued at $50 million thanks to appearances on Keeping Up With The Kardashians and her clothing brand, Good American.
