"He's drinking every single day," a source tells In Touch. "He drinks vodka martinis on the rocks so everyone assumes he's drinking water. The whole family thinks he should go to rehab. Maybe he thought he could quit cold turkey, but he can't."
"Kourtney is afraid that if he doesn't get help, he could end up dead," the insider claims, adding that the mother of Disick's children "asks him daily" to check himself into rehab.
The situation has reportedly gotten so bad that Kourtney has threatened to leave Scott if he doesn't give up the sauce.
Unfortunately, her threats obviously haven't done much good. Witnesses say Disick looked "exhausted and rough, like he was hungover" at a recent public appearance, after being spotted partying at a club the night before.
