This season on Kourtney & Khloe Take The Hamptons, Kardashian expressed concern after Disick swallowed an entire bottle of pills and had to checked himself into a hospital.
"I don't think he's probably ever taken this many sleeping pills after drinking," she said. "My biggest fear is that he continues on this road. I don't know where that could lead."
As for rehab, RadarOnline.com has reported that Disick secretly checked in for treatment after his hospitalization. However, he continues to party.
