Kourtney Kardashian is reportedly "not shocked" that Scott Disick isn’t taking to the fact she’s happy with another man – despite the fact the former pair haven’t been together since 2015.

On Monday, Kardashian’s ex-boyfriend, model Younes Bendjima, 28, posted an alleged direct message he claimed was from Disick to his Instagram Stories in which the entrepreneur appeared to shade her public affection with Travis Barker.

The message was sent alongside a photo of Kardashian – who is the mother of Disick’s three children – straddling Barker on a boat. "Yo is this chick ok!???? Broooo like what is this. In the middle of Italy," Disick allegedly wrote to Bendjima, who then turned around and shared the DM for the world to see.

Bendjima allegedly wrote back, "Doesn’t matter to me as long as she’s happy," adding, "PS: i aint your bro."

Now, a source is telling People magazine that Kardashian was none too pleased with Disick covertly attempting to buddy up with Bendjima at her expense – and she plans to confront him on it.

"She was surprised, but not shocked," the source says. "Scott has always had a difficult time accepting that Kourtney is happy with someone else. He is especially threatened by her relationship with Travis."

The insider maintained that Kardashian and Disick's children – sons Mason, 11, and Reign, 6, and daughter Penelope, 9 — "love" Barker, 45, "which has been hard for [Disick]." 

"Yet, he and Kourtney have been getting along," the source continued. "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."

Bendjima, who dated the Poosh founder from 2016 until their split in 2018, also wrote over the screenshot of the alleged direct message, stating: "keep the same energy you had about me publicly, privately."

In a follow-up slide on his Instagram Story, Bendjima wrote, "couldn’t miss this one. He been playing around for too long, tired [sic] to stay quiet and be the nice guy."

Disick has yet to publicly respond to Bendjima, who many believed had also shaded his ex in a shared-then-deleted Instagram Story post back in April.

"Shamelessness has become so normal in today’s society that modesty has become strange," Bendjima posted at the time in the wake of Kardashian sharing a photo of herself donning a thong bikini and kissing Barker.

Barker appeared to react to the news by posting a meme to his Instagram Story of Ray Liotta's character from "Goodfellas" laughing hysterically.
