Although Disick appears to be happy with his rumored girlfriend, 19-year-old British model Ella Ross, his friends say the romance is just to get back at Kardashian for hurting and "betraying" him.
Disick had been trying to win Kardashian back for months by cutting back on partying and whisking her off on a romantic vacation.
Disick wanted to prove to his longtime love of nearly a decade that he could stay sober and be a great dad to their three children -- Mason, Penelope, and Reign.
Disick allegedly feels that Kardashian led him on by allowing him to think there was a chance of reconciliation.
Once he learned of Kardashian and Bendjima's relationship, Disick reportedly lost it and began binge drinking both at his home and at nightclubs -- including TAO on Cinco de Mayo and The Peppermint Club earlier this week.
Sources claim his house has turned into a non-stop, alcohol-fueled party for weeks now.
Kardashian has been involved with Bendjima since October 2016, TMZ reported.
However, a source recently told Us Weekly that the reality TV star and Bendjima "are not serious."
Kardashian reportedly pulled the plug on her relationship with Disick in July 2015 when he was spotted getting touchy-feely with his ex-girlfriend Chloe Bartoli in Monte Carlo.
Kardashian also struggled to deal with Disick in light of his on-again, off-again substance abuse issues.
As for his career, Disick is reportedly filming a home-flipping TV series pilot executive produced by Kardashian's mother Kris Jenner.
His friends told the website Disick has been able to juggle his professional life with drinking and partying for years now.
