The colorful bash featured Octonauts-themed decorations and treats, including a pool surrounded by giant bubbles and floating pastel-colored balloons, performers in Octonauts costumes, personalized cupcakes, and ice cream sandwiches.

Of course, the Kardashian-Jenners were in attendance, with Kylie Jenner also documenting the affair on her TikTok which featured a rare look at her baby boy Aire.

But did Khloé invite her unfaithful ex and True's dad, Tristan Thompson?

Well, the former NBA star was spotted at the epic bash, per Khloé's BFF Malika Haqq's IG story.

Tristan was seen keeping a low-profile and enjoying some cake at his daughter's party while sporting an-all white ensemble.

However, that seems to be the only footage of Tristan, who's been sparking reunion rumors with KoKo and ironically is her new neighbor.

Regardless, it's good to see both parents present for their daughter's special day.
