The late-night host laid into Khloe Kardashian's baby daddy Tristan Thompson, with whom Jordyn allegedly cheated, saying he's "not even a great basketball player."
To say this whole thing is a mess would be a dramatic understatement, and it was almost too much for Busy to handle. She literally flopped onto her couch at the top of "Busy Tonight" on Thursday. And she had a strong message for Jordyn, which she delivered directly into the camera.
"Jordyn, Jordyn, Jordyn, you had one job," she said. "As a professional celebrity BFF, all I have to say is, There are rules."
For newbies to this story, and Gwyneth, Tristan is Kylie's sister Khloe Kardashian's boyfriend and father to her child True, who was embroiled in another cheating scandal last April, literally days before True's birth.
Busy went on to chastise Jordyn, who has allegedly moved out of Kylie's house where she was staying, saying, "Jordyn if this is true, you should have known better. Tristan's not even a great basketball player, from what I understand."
She then had a word of advice for anyone who might find themselves in Jordyn's situation Sunday night. "If you're going to cheat with someone from Cleveland, at least make sure it's a starter."
Khloe has been putting on a brave face since the story broke while continuing to fulfill her professional obligations. The reality star attended the opening of PrettyLittleThing in Los Angeles on Wednesday night, alongside best friend Malika Haqq.
Kardashian looked fierce in a sweater from the apparel line and leather pants and was seen interacting with "Vanderpump Rules" star James Kennedy inside the bash. She has reportedly severed ties again with Tristan over this latest cheating allegation, perhaps this time for good.
As for Kylie, TMZ reports she's been seen hanging with another friend, Heather Sanders. It is unclear where things stand between her and Jordyn, or even if they've spoken about the alleged incident.
