TRISTAN Thompson wished his son, Tatum, a happy birthday, but fans took issue with how he did it.
Khloe Kardashian's ex shared photos of him and True, 6, on Instagram to celebrate the occasion.
"Happy birthday Tatum!! Man time goes by so fast! I can’t believe you’re already two years old!" Tristan on Sunday.
"I am so blessed and honored to be your dad. Your energy and charisma light up the room."
"Thank you for being such an amazing son and brother to your mommy and sister. Watching you grow everyday makes my heart happy," he went on.
"Continue being the angel you are son. Daddy loves you so much."
The photos in the post featured Tristan, 33, with Tatum, 2, and his daughter, True, at different events, as well as solo shots of just Tatum.
He shares both of those children with Khloe, 40.
'SAME LOVE AND RESPECT'
Although the post was heartfelt and meant no harm, some fans took issue with it.
"All your children should get the same love and respect," one of his followers wrote.

"Exactly," a fan replied to them.
Tristan has two other children - Prince, 7, with ex-girlfriend Jordan Craig, and Theo, 2, with model Maralee Nichols.
He had Theo when Khloe was still pregnant with Tatum.
"You have another little boy out there that would probably love to have his dad, not deny him," another fan commented.
"Don't forget about your other kid man...! Remember the other little boy that is the same age as Tatum..?!" said another.
TATUM'S BIRTHDAY PARTY
Along with sharing a post for Tatum, Tristan also reshared Kris Jenner's post for him and others who wished him a happy birthday.

Khloe and Tristan were first linked in 2016 after attending a party in Miami together.
In 2018, they welcomed their first child, True.
Tristan was then caught cheating on Khloe multiple times during her pregnancy.
They split after it was revealed that he kissed Kylie Jenner's best friend Jordyn Woods at a party.
The pair reconciled in 2020 and ended things in 2021.
Six months after they ended, it came to light that Tristan fathered a child with Maralee Nichols while he and Khloe were together.
Just months later in July 2022, Khloe revealed that the pair were expecting their second child, son Tatum, via surrogate.
The pair are currently co-parenting and claim there is no romantic connection between them.
He then shared photos and videos from Tatum's birthday party to his Story.
The party was dinosaur-themed and called Tatum Two-a-Saurus.
There was a balloon arch with dinosaurs as guests entered the party.
Around the pool were balloons and leaves in blue, tan, and green.
There was also a sign that said "T-Rex Zone (T for Tatum)."
The party also featured cookies and rice krispie treats decorated with a big number two, plus dinosaur heads, and mini dinosaur replicas.
