Tristan Thompson is under fire once again, this time for noticeably excluding his son Theo from a recent Instagram post.

The 34-year-old Cleveland Cavaliers player took to social media on Saturday to celebrate his and Khloé Kardashian’s daughter True’s 7th birthday with a heartfelt message and a carousel of sweet family photos.

“Happy birthday Twinny!! My TuTu is 7 today!! I can’t believe how time flies,” he wrote. “Momma, you are literally the light that shines bright in my life. When I see you, I see Mommy, aka GiGi. True, you bring your brothers, mommy, and all your cousins so much happiness you literally spark any room you walk in.”

“You have the best soul ever. I’m so blessed to have you as my daughter. Keep being amazing each and every day. Daddy always got you. I can’t wait to play tag and jump on the trampoline. I love you Twin.”

The post included images of Thompson with three of his four children: Prince, 8, whom he shares with ex Jordan Craig; and True and Tatum, 2, both of whom he shares with Khloé Kardashian. Also pictured was Dream Kardashian, Khloé’s niece, in a throwback from Tatum’s dinosaur-themed birthday party last summer.

“Boy where yo other kid,” one user asked.

“You’re missing one of your children,” another commented, while a third noted, “Where’s the other kid???? He has 3.”

Others criticized the Cavaliers player for what they viewed as emotional neglect, expressing concern over the long-term impact. “Imagine in a few years that kid makes contact because he is old enough to understand THIS whole messed up situation??!!!” one commenter wrote.

Theo, now 2, was born in December 2021, just one month after Thompson and Kardashian conceived their second child via surrogate. Thompson initially denied paternity, but confirmed he was Theo’s father in January 2022.

“Today, paternity test results reveal that I fathered a child with Maralee Nichols,” he said at the time. “I take full responsibility for my actions.”

He added, “Now that paternity has been established I look forward to amicably raising our son. I sincerely apologize to everyone I’ve hurt or disappointed throughout this ordeal both publicly and privately.”

He also issued a public apology to Kardashian, stating she did not deserve the “heartache and humiliation” caused by his actions.

“Khloé, you don’t deserve this. You don’t deserve the heartache and humiliation I have caused you,” he said at the time. “You don’t deserve the way I have treated you over the years. My actions certainly have not lined up with the way I view you. I have the utmost respect and love for you. Regardless of what you may think. Again, I am so incredibly sorry.”

In a confessional interview on the reality television show, “The Kardashians,” Khloé said, “I find out what Tristan is doing with the rest of the world. A courtesy would be not doing it. But fine, if you do it, you are not even going to give me a f-cking heads-up before the rest of the world? It is just an additional slap in my face. It is humiliating. I am embarrassed.”
