Hold. The. Phone. News of Tristan Thompson‘s cheating leaked just days before Khloé Kardashian gave birth to their daughter, True, but apparently, the NBA baller wasn’t the only one who was unfaithful. A source tells In Touch exclusively that the Good American designer also hooked up with a famous face — her ex-boyfriend, French Montana!

“Khloé cheated on Tristan with her ex French Montana. They hooked up as early as several months ago,” a source tells us. Khloé, explains an insider, wanted revenge. “Plain and simple, it was payback time.”

Photos and videos of the Cleveland Cavaliers star kissing, motorboating, and getting groped by women at a club were released on April 10, while Koko was in his hometown of Cleveland pregnant and alone.  

“Tristan’s f–ked up big time. He knows it. And Khloé’s pissed!” the source told Life & Style at the time. “Khloé’s done. She’s so f–king done. Her stomach hurts so bad and it’s not from the pregnancy. She could kill Tristan right now.”

But perhaps she quickly forgave the 27-year-old because she was cheating herself. “She was hurting and lonely, so she turned to French for comfort,” explains the insider. “Did it make her feel better that she was also getting even with Tristan? Of course it did. It’s like that old saying: What’s good for the goose….”

Koko, 34, and French, 33, dated from 2013-2014, and he even made regular appearances on KUWTK. In fact, he was one of the longer, more public partners the reality star had after her marriage to Lamar Odom crumbled.

And Khlo’s sisters were all for it. “I’m told that sisters Kim [Kardashian] and Kourtney [Kardashian] knew about Khloé’s rendezvous and secret ongoing friendship with French and completely supported it,” explains the insider, who says Kim, in particular, has been clear that if Tristan wasn’t putting a ring on Khloé’s finger and being careless about his affairs, “then she’s free to do whatever the hell she wants.”
