The reality star invited the NBA player to True's lavish first birthday celebrations, just weeks after she called time on their relationship amid reports that her partner had kissed family friend Jordyn Woods at a party.
She has since shared a cryptic quote aimed at men, which talks about being a good father.
The cryptic message read: “Dear men. Close your eyes. Imagine you have a daughter. Imagine she is dating a guy just like you. Did you smile? No. Then change.”
The post comes after Thompson briefly appeared on Kardashian’s Instagram stories in an awkward video of him attempting to take True out of her hands at the lavish party earlier this week.
In the clip, Kardashian turned away to chat to other children at the party, not giving Thompson the opportunity to grab the tot.
Despite the cringe-worthy encounter, Thompson shared an affectionate video of himself smothering his “princess” True in kisses on Instagram.
He captioned the post: “My princess. I love you soo much.”
Failing to hold back her tears, she hit out at her former flame for not respecting her.
She told the camera: “It just sucks that it has to be so public. I’m not just a TV show this is my life. Tristan might love me but he has no respect for me whatsoever.”
A later clip showed the star screaming down the phone about how her family has been “ruined” by the scandal.
According to Us Weekly, Woods was left feeling “mortified” to have to “relive” the drama through the trailer.
