VIDEO: Watch the Kardashian-Jenners React to Tristan Thompson's Cheating Scandal in 'KUWTK' Promo

While fans know all about the Tristan Thompson-Jordyn Woods cheating scandal which took place in Feb. 2019, we have yet to see it aired on Keeping Up With the Kardashians. However, this upcoming Sunday will change that. A newly-released promo shows how the family reacts to the news.

In the clip, as reported by E! News, Kim Kardashian's best friend Larsa Pippen calls to tell her that Tristan and Jordyn were "all over each other" the night before. Then Kris and Kim talk about it. Kris says, "We just need to figure out what the whole, full story is." Kim tells her mom, "Tristan admitted it!"

In another shot, Kylie Jenner says: "I'm just like, 'What were you thinking?'" In true teaser-mode, we don't know if Kylie is talking to Jordyn or talking to her sisters about the cheating scandal. A betrayed Khloé is also heard saying, "I knew who he was, I never in a million years thought that's who she was." In between tears, she adds, "It just sucks it has to be so public."

We know that Jordyn moved out of Kylie's house after the news came out and that Tristan and Khloé broke up for good--but more will be revealed in the TV series.

Keeping Up With the Kardashians continues this Sunday with the first half of its two-parter finale.
