Scott Disick, the ex-partner of Kourtney Kardashian, has returned to rehab to combat his ongoing issues with drug and alcohol abuse.

Scott Disick Back In Rehab

Disick, 32, voluntarily checked himself into luxury drug and alcohol rehabilitation center Cliffside Malibu over the weekend, according to People magazine. According to a source, Disick was motivated to seek treatment so that he can get visitation with his kids – Mason, 5, Penelope, 3, and Reign, 10 months.

“He wants to make it stick this time because he has come close to losing everything,” the source claims. Kardashian reportedly “thinks he is a drunk mess” and plans to seek sole custody unless he gets his act together.

Disick’s struggle with sobriety has been well documented on Keeping Up with the Kardashians. The reality TV star’s last stint in a rehab was back in March, when he checked himself into the Rythmia Life Advancement Center in Costa Rica.

“I realize my issues are bigger than me and I’m ready to truly remedy this struggle I continue to battle,” Disick said in a statement at the time.

A few months after Disick’s short stay at the rehab center, he was pictured drinking on vacation in Monte Carlo with Chloe Bartoli. The pictures, which showed Disick getting tactile with the LA-based stylist, ultimately led to his split from Kardashian.

While Disick battles his addictions in rehab, Khloe Kardashian‘s estranged husband Lamar Odom remains in critical condition after an alleged accidental drug overdose at a Nevada brothel.
