"Kourtney is disappointed that he engages in drama when they have been doing well co-parenting. She doesn't get why he felt the need to reach out to Younes. She will confront him about it. For now, she continues to enjoy her trip with Travis." In the message to Bendjima, Disick allegedly sent a photo of Kardashian straddling Barker and wrote, "Yo is this chick ok!???? Broooo like what is this. In the middle of Italy." Bendjima, 28, allegedly responded: "Doesn't matter to me as long as she's happy. P.S. I ain't your bro." He then shaded Disick further in a note he added to the screenshot. "Keep the same energy you had about me publicly, privately," he wrote. "Couldn't miss this one. He [had] been playing around for too long, [I'm too] tired to stay quiet and be the nice guy."
