It appeared that the KUWTK star, 34, and their baby were with Thompson, 27, in Cleveland, Ohio for the holiday—and Khloe was cooking for her disgraced man.
"I'm soo blessed," the basketball hunk wrote in a caption of a photo of the three of them posted on Thursday's turkey day.
The November 22 Instagram picture shows Thompson holding True, seven months, as he has his hand affectionately around Khloe's waist.
Thompson added, "Happy thanksgiving from my family to yours #GiveThanks #blessed."
Thompson implied that he and Khloe celebrated in Cleveland as he also did an Instagram Live video around a kitchen full of food.
He later added an Instagram Story in which he called Khloe "this fine ass chef."
Then the Cleveland Cavaliers star got annihilated in his Instagram comments section, as followers recalled his notorious cheating scandal first reported by Radar.
Thompson was unfaithful to Khloe with a woman at a club days before he was about to become a dad.
Khloe is reliving the drama in current episodes of KUWTK. In one, she brands Thompson "a complete piece of s***" after his cheating news broke while she was expecting their baby.
One Thompson commenter wrote, "You don't deserve what you have" after seeing the Thanksgiving Day happy family shot.
Another wondered, "What happened to that broad from the club?"
And someone else opined, "Ya blessed she took you back."
In fact, sources have told Radar Khloe has thought about moving from Los Angeles to Cleveland where her man plays basketball.
But she's also talked about having trust issues with Thompson.
Still, on Thanksgiving, all seemed well as Khloe shared some Instagram Stories displaying all the food she had cooked and a table setting with pink and white decor.
She added a photo of herself with Tristan and their daughter, captioning it, "True and I were hungry."
