"Scott is mortified that Younes shared his private DM message," an insider told E! News. "He had a low moment and was looking to someone who could relate to his feelings, and immediately regretted sending that message."
"Scott Disick is still very bitter about Kourtney and Travis' relationship. He wants her to be happy, but behind closed doors, he will always have regrets about their relationship and why it didn't work out," the insider told the publication. "He is bitter because he's never seen Kourtney this serious about someone."
The 37-year-old allegedly messaged the model a photo of the Poosh founder and the Blink-182 drummer sharing a steamy kiss. "Yo is this chick ok!???? Broooo like what is this. In the middle of Italy," he wrote.
"Doesn't matter to me as long as shes happy. PS: i aint your bro," Bendjima replied.
"Scott never liked Younes and totally acted irrationally," the insider said. "He regrets reaching out to him."
Disick is said to have spoken to the 42-year-old about what happened. "Kourtney doesn't care and doesn't want to deal with the drama," the source explained. "She thinks they both acted immaturely and has moved on from it."
While the reality star did not directly comment on the drama, she shared a Poosh article on her Instagram Story on Wednesday, September 1, about getting over someone who "treated you BADLY."
Meanwhile, Kardashian and the 45-year-old were enjoying a European vacation. The brunette beauty shared snaps from Disneyland Paris on her Instagram Story on Wednesday, September 1. Hours later, she shared a clip of the "rose petals and welcome home signs" her children greeted her with when she arrived home.
