There's trouble brewing in the Kardashian household once again, as evidenced by Sunday's episode of "Keeping Up with the Kardashians." The eldest sibling, Kourtney, was outraged that the father of her children and her former flame, Scott Disick, brought a woman to their recent family trip to Costa Rica. The 38-year old entrepreneur, reality TV star, and mother of three accused Disick of "playing the victim" when confronted about the issue, PEOPLE reported. The explosive new episode showed Kardashian teaming up against Disick once again, but Kourtney believes that this is the last straw.

Scott Disick admits he is a 'horrible sex addict'

On Sunday's episode of "Keeping Up with the Kardashians," Scott Disick admitted that he is a "horrible sex addict," which was the reason why he could not stay loyal to Kourtney Kardashian. Kourtney commented, "Scott’s so lucky, because I am the coolest baby mama on the planet." The eldest Kardashian added that it was about time to confront her former partner and tell him that there was no hope in reconciling with him following the stunt he pulled in Costa Rica. She said, "I need to have a conversation with him just to finally say we will never be back together. It’s probably better for both of us."

Kourtney Kardashian confronts Scott Disick, tells him 'it's done'

There's no hope for the former flames of "Keeping Up with the Kardashians," as Kourtney finally put a lid on any hopes that they would reconcile.

Disick, on the other hand, seemed to be holding out hope that the pair would get back together. But when Kourtney said "it's done," he responded with "That's all I've ever wanted you to say."

How will Kourtney and Scott co-parent moving forward?

The "Keeping Up with the Kardashians" stars are parents to three children, Mason Dash, Penelope Scotland, and Reign Aston, who shares his older brother Mason's birthday.

Some viewers believe that their fights were all just for the cameras. But there seems to be one thing missing in Scott's life -- a wife. Back in 2011, he intended to propose to Kourtney, but the latter did not want to get married because things were good at the time. According to E! News, Disick shared his thoughts on being a single parent, saying, "Every night, you go to bed with our kids and I have to sleep alone, sad and miserable. That's my life." It seems that he'll have to get used to it, though, as Kourtney no longer sees a future with her former flame.
