Oh no, he didn’t! Kourtney Kardashian had a bone to pick with her baby daddy Scott Disick, 35, after finding out that he introduced their kids to his 20-year-old girlfriend, Sofia Richie, without reaching out to her first. In a sneak peek at Sunday’s episode of Keeping Up With The Kardashians, the exes get into a tense argument over his decision.

Their dispute got pretty awkward after Scott called his former flame “annoying,” which prompted her to tell him “be appreciative of what you have” because she still makes him a part of the KarJenner family. Kourtney, 39, felt like Scott was doing whatever he wanted without giving her any consideration, but he felt like she was being hypocritical. “Live my life the exact same way you’re living it?” he clapped back. 

Kourtney gave him a piece of her mind, saying: “It’s called giving someone a heads up and having a respectful conversation — giving someone the respect.” And Scott continued to fire back, asking: “Do you think you’re difficult, or no? Do you think you’re overly controlling? Do you think there’s any chance you could ever be in denial about anything?” On the plus side, it looks like they’ve worked out a better co-parenting arrangement since then.

“It helps that Kourtney now trusts Sofia,” a source told People. “The kids are allowed to spend time with her. So far, the kids are giving Kourtney good reports about Sofia.” The couple has been going strong since last fall and Sofia recently revealed they’re “very happy” together during an appearance on Australia’s The Morning Show. Even though some fans will always ship Scott and Kourtney, it looks like they’ve both moved on romantically for now!
