Tristan, father of Khloe Kardashian's daughter True Thompson, was also missing from the lavish birthday party
Khloe Kardashian's gorgeous, cat-themed party for daughter True Thompson's fourth birthday garnered massive attention online.
However, some eagle-eyed fans noticed that she has stripped several key family members from True's fourth birthday guest list.
The fashion mogul also took to his Instagram handle and shared a few snippets and pictures of him enjoying his daughter's special day.
From the pictures shared, fans noticed that True's father, Tristan Thompson, was missing from the party.
The basketball player, who had an affair with Khloe due to multiple cheating allegations, was playing a basketball game at his daughter's party.
However, Tristan's five-year-old son Prince, whom he shares with his ex Jordyn Craig, was seen celebrating with his younger brother.
Other young guests at the extravagant party included True's cousins, including Kim Kardashian's children North, eight, Saint, six, Chicago, four, and two-year-old Psalm and Kylie Jenner's oldest daughter Stormi.
While Khloe's mom, Kris Jenner, attended True's birthday party, fans noticed that Caitlyn wasn't invited to her step-granddaughter's birthday.
Khloe's brother Rob, 35, was also missing from photos and videos of True's lavish bash posted on social media.
