"What a piece of s–!" momager Kris Jenner yells while looking through the pictures of the rumored rendezvous.
"I worked so hard to keep this family together," Kourt tearfully tells Kim Kardashian.
The photos seemed to be the last straw for the couple, whose rocky relationship has been documented for years on the reality show.
Kardashian and Disick were together for nine years and have three children – Mason, 5, Penelope, 3, and Reign, 9 months.
Not only will fans get to see the drama between Kourtney and Scott, but they will also get a front row seat as the famous family adjusts to Caitlyn Jenner's transition.
"The only thing is I haven't met her," Kendall Jenner says to her sisters. "I'm not gonna be fully supportive if she's not fully supportive of our mom," Khloe Kardashian declares.
"I still have a long way to go before I can process all of this," Kris says before admitting to Kim, "He's gone."
See all the drama go down on "Keeping Up With the Kardashians" on Sundays at 8 p.m. ET/PT on E!.
