Khloé Kardashian pulled out all the stops for her son Tatum's third birthday!

On Monday, July 28, Khloé, 41, shared snaps on her Instagram Stories from her and ex Tristan Thompson’s son’s big birthday bash.

The Mickey Mouse Clubhouse-themed party featured a huge balloon archway that greeted guests with a banner reading, “Tatum’s Clubhouse.”

Guests were then entertained by various Disney characters, including Donald Duck and Daisy Duck, with Tatum captured high-fiving Mickey Mouse before taking a photo with him in front of a themed-backdrop reading, "Tatum Turns 3."

"Wow, we have Donald and Daisy,” Kardashian said as she filmed the Disney ducks dancing.

An incredible spread of food was laid on by chef Natalie Pukasemvarangkoon, with table laden with fries, mini sliders, Mickey Mouse-themed toasties and waffles, corn on the cobs and popcorn.

The birthday boy was also treated to an enormous Disney-themed cake with his name “Tatum” iced on the front of some Mickey Mouse ears.

 

Tatum’s auntie Kim Kardashian also shared a snap of the birthday cake on her Instagram Stories.

Meanwhile, Khloé revealed another cake, shaped into what appeared to be Sleeping Beauty's Castle, for Tristan's brother Amari, who celebrated his 19th birthday on July 27. A clip later shared on Khloé's Instagram Stories showed the party singing "Happy Birthday" to Amari as she blew out his candles.

The clip was followed by guests singing "Happy Birthday" to Tatum as Khloé carried her little boy and dad Tristan stood next to them and helped blow out his candles, with Khloé and Tristan’s eldest daughter True Thompson, 7, seen next to the cake alongside her cousins Dream Kardashian, 8, daughter of Rob Kardashian and his ex Blac Chyna, and Stormi Webster, 7, the daughter of Kylie Jenner and her ex Travis Scott.

The party also had a Disney-themed sensory spot and arts and crafts section by Little Artist Party, a “Tatum’s Candy Bar” and a Stoney Clover Lane stand with pencil cases that featured the names of all the kids.

True was seen performing a dance to Bruno Mars and Rosé’s song “APT” alongside Dream, with the girls then joined by Tatum, who was dressed in jeans printed with Disney characters, as he jumped up and down and danced beside them in the backyard.

The backyard had been transformed for the party, with the swimming pool filled colorful pastel Funboy floats and tasseled balloons strung above the water.

Though not seen in the snaps and clips shared on Instagram by Khloé, her sister Kourtney Kardashian Barker and her mom Kris Jenner shared celebratory posts for Tatum on social media.
