Khloé Kardashian and Tristan Thompson are fed up with all the rumors.

According to E! News, the former couple reportedly sent a cease and desist letter to a woman claiming the NBA star is the father of her child.

In a letter sent by their lawyer Marty Singer, the two are demanding that this woman — named Kimberly Alexander — “immediately stop defaming them with malicious defamatory lies and specious fabrications.”

The paternity fiasco began when the blog Gossip of the City published copies of laboratory paperwork suggesting that Tristan took a paternity test in January 2020.

The report also included alleged text messages showing an argument between him and Kimberly over DNA testing.

However, the former couple said that the test in question turned out to be negative.

“After it was indisputably established by a paternity test performed by one of the most reputable labs that Mr. Thompson is not your child’s father, we thought that would be the end of this,” the letter read, according to E! News. “Instead, you have continued to spread outrageous lies about my clients, including ridiculous fictional conspiracy theories that you conjured up claiming that my clients supposedly somehow falsified the paternity test results since members of the Kardashian family had previously used the same trustworthy lab.”

Well clearly they’re doing everything they can to make this stop.
