Clearly he's not headed home to Kourtney Kardashian and the former couple's three children!

On Tuesday Scott Disick checked out of rehab and posted the photo above with the caption, “Private aviation is my motivation." He would post that as a caption...

Disick checked into Malibu’s Cliffside rehabilitation center for drug and alcohol addiction exactly a month ago, and just the other day Kourt brought the couple's three children, Mason, Penelope, and Reign to visit her estranged baby daddy. Interestingly enough, Kris Jenner was also with them, so we're thinking reality TV cameras may have been rolling. I mean, why else would PMK be supervising?

This is the second time Disick has sought treatment this year, and Us Weekly reports that the reality star had been abusing cocaine, Xanax, and alcohol in the days before he checked in to the facility.

"He does a lot of coke. He takes downers and benzos [benzodiazepined, such as Xanax], which slow your heart after you've sped up. He takes Ativan to knock himself out at the end," a source told the magazine. Another insider told the mag earlier this summer, “Scott is running off the rails. He can’t keep going like this. It’s scary.”

Apparently Lamar Odom's recent hospitalization scared Disick a bit, and brother-in-law Kanye West stepped in as well. “Kanye told him he needs to man up and go to rehab,” another source told Us, adding that Kardashian told Disick he had to get help if he wanted to be a part of their kids’ lives. Aww, maybe he does care after all...
