This is Disick's third stint in a rehab facility this year. He spent a brief amount of time in a Costa Rica facility in March for hallucinogenic treatment and checked into a Florida rehab center in July.
Sources told TMZ that Disick has distanced himself from partying friends and hopes to get clean for his kids. Kourtney Kardashian currently won't allow Disick to have unsupervised visits with their three children until he's clean. The two split up over the summer.
In other Kardashian-related news, just a few hours before Disick's rehab was reported, it was revealed that drugs were found in Lamar Odom's system after he was found unconscious in a Nevada brothel. Odom had been married to Kourtney's sister Khloe for four years, though they have yet to finalize the divorce they filed for in December 2013.
