Fans immediately noticed when her estranged baby daddy slid into her comments and they let him have it.
The Good American founder's fans were quick to come to her defense and slammed the NBA player for even laying eyes on her page.
Blowing up Khloé's comments, they left salty replies for her ex.
"why try now???" one fan asked. "Men really think they can get anything they want huh."
So many people had the same question, why now?
"why why whyyyyyyyy just leave her alone you've reached a point of no return," another reply read.
Some straight-up quoted Queen Bey in their responses to Tristan.
"all of a sudden boy BYE!!!" one fan wrote. "really Tristan," asked another.
Khloé's fans can't even fathom that Tristan had the audacity.
"get your diamond back and learn to be faithful to her," a fan told the NBA star.
"Just let it go bruh," laughed another.
Khloé and Tristan have a rocky past.
The couple, who were first linked in September 2016, have dealt with infidelity in their relationship prior to cheating with Jordyn Woods.
Anyone remember, Tristan straying right before she gave birth?
"KUWTK" viewers are deeply invested in their relationship because they've watched all their drama unfold this season.
Fans have been there every step of the way, from the moment Khloé found out he cheated on her with Kylie Jenner's former BFF, to the aftermath of trying to co-parent their daughter following the epic fallout.
As of this post, no one in the KarJenner family has responded to Tristan's thirsty comment.
