Scott Disick breaks down crying in an emotional sneak peek of Sunday’s upcoming Keeping Up With the Kardashians episode. In the clip, the self-proclaimed Lord cries while apologizing for embarrassing the family.

"This is the stuff that I don't understand: You say, ‘Oh, I don't have a family, and I don't have all these things,' and then we give you one. Why do you destroy it?" an angry Khloe Kardashian questions Disick.

"I'm sure you guys have heard a lot of horrible things about me that I should have just been honest with, but I was too ashamed that I was going to hurt everybody in this family and not just her," Disick, 32, says, referring to his ex-girlfriend Kourtney Kardashian. "I've apologized to Kourtney a hundred times, but I've never apologized to like all of you for letting all of you down and embarrassing you guys … I understand I need to help myself before I can help her or my kids.”

Disick, whose parents died within months of each other, checked into a rehab facility in October after Kourtney, 36, broke up with him in July. As previously reported, Disick was photographed looking flirty and suspiciously close to his ex-girlfriend Chloe Bartoli while on vacation in the South of France prior to their split.  

Since seeking treatment, Kourtney has allowed Disick to spend time with their three kids Mason, 6, Penelope, 3, and Reign, 12 months. As previously reported, the eldest Kardashian sister gave her ex an ultimatum to get sober and has remained cordial with the reality star simply for their children’s sake.

Watch the clip above. Keeping Up With the Kardashians airs Sundays on E! at 9 p.m. EST.
