SCOTT Disick is reportedly “still very bitter” about Kourtney Kardashian’s relationship with Travis Barker.
The Talentless founder, 37, feels “mortified” about the nasty DMs he sent mocking his ex’s PDA with the Blink-182 drummer.
Scott – who shares three kids with the KUWTK star – appeared to take offence to photos of Kourtney straddling Travis and making out with him on a boat in Sestri Levante, Italy.
The reality star allegedly messaged Kourtney’s other ex, model Younes Bendjima, 28, to troll her.
“Yo is this chick ok!???? Brooooo like what is this. In the middle of Italy,” he apparently private messaged Younes on Instagram.
Younes – who dated Kourtney from 2016 to 2018 – clapped back: “Doesn’t matter to me as long as she’s happy. PS: I ain’t your bro.”
Following the exposed DMs, sources claimed Scott is “bitter” about Kourtney and Travis and still has regrets about their own 10-year relationship ending in 2015.
“Scott Disick is still very bitter about Kourtney and Travis’ relationship,” an insider told E! News.
“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.
“He is bitter because he’s never seen Kourtney this serious about someone.”
As for the leaked messages, the source claimed: “Scott is mortified that Younes shared his private DM message.
“He had a low moment and was looking to someone who could relate to his feelings, and immediately regretted sending that message.”
Travis – who enjoyed a romantic Italian getaway with Kourtney – subtly responded to Scott’s dig.
He appeared to mock Scott by sharing a photo of actor Ray Liotta hysterically laughing in the film Goodfellas on his Instagram Stories.
Kourtney also appeared to make her feelings known by sharing a post about people who “treat others like s**t”.
The post on her Poosh lifestyle website’s Instagram account read: “Still in love with someone who treated you like s**t? Been there.”
Scott and Kourtney dated on and off for a decade and are parents to Mason, 11, Penelope, nine, and Reign, six.
The Poosh founder began dating her longtime friend Travis earlier this year and the couple have become known for their PDA-filled posts.
