Tristan Thompson is being “open” and transparent with ex Khloé Kardashian.

A source tells PEOPLE that Thompson immediately told Kardashian when a woman requested the NBA star take a paternity test after claiming he is the father of her child.

“Tristan has been open with Khloé from the beginning when it comes to the paternity test,” says the source. “He told her that he needed to take the test, but also that he didn’t believe that he is the dad.”

Earlier this week, Thompson, 29, and Kardashian, 35, sent a cease and desist letter to demand the woman, Kimberly Alexander, to “immediately stop defaming them with malicious defamatory lies and specious fabrications,” according to documents obtained by E! News.

In the letter, sent by the former couple’s lawyer Marty Singer, the attorney confirmed that Thompson took a paternity test in January 2020 but said the results were negative.

It’s funny how their source wishes to remain anonymous. 

I mean it’s obviously Kris Jenner spinning her web.
