Following his hospital stint for alcohol poisoning last month, Scott Disick vowed to remain sober until his longtime girlfriend Kourtney Kardashian gives birth to their third child.

"He stopped drinking cold turkey -- and promised he won't drink again until after Kourtney gives birth," said an Us Weekly source. "Scott knew he had hit rock bottom."

On June 22, Disick was rushed to the hospital for severe alcohol poisoning following a night of binge drinking in the Hamptons, reports TMZ.

Doctors tested Disick for drugs and alcohol and later concluded that Disick's illness was solely due to alcohol poisoning.

Us Weekly suggests that Disick's erratic behavior and excessive drinking may be due to the recent death of his parents.

"He went through a dark place," said the Us Weekly source.

But now, despite his alleged vow to remain alcohol-free, it seems that Disick may be slipping through the cracks once again.

The Daily Mail reported on Friday, French Montana posted a photo of himself, rapper Fat Joe, and Disick holding a wine glass while partying in the Hamptons.

French Montana captioned the photo, "Out here hampin @frenchmontana @fatjoe."

Khloe Kardashian's new beau then posted more photos from the "turnt up" celebration in the Hamptons for Jennifer Lopez's 45th birthday.

"Turnt up in the hamptoms happy bday to the queen @jlo #southbrox" Montana captioned his selfie photo with J.Lo.

Although the drink of choice in Disick's wine glass remains unclear, media outlets such as TMZ suspect that Disick may have broken his vow and chose to drink alcohol that night.

If this is true, Disick's drinking may be the final straw for Kourtney who allegedly threatened to leave Disick if he sticks to his drinking habits according to an Us Weekly source.
