Scott Disick has left rehab. The 'Keeping Up With the Kardashians' star, 32, checked out of Cliffside Malibu in California, where he's spent the last five weeks recuperating, on Tuesday (10.11.15) and couldn't help but brag about his release by uploading a photograph of him boarding a private jet. He captioned the image: "Private aviation is my motivation." The troubled star sought treatment at the luxurious rehabilitation centre over a month ago after three failed attempts to curb his drug and alcohol issues in the past. However, news that Scott has left the facility will unlikely go down well with his ex-girlfriend Kourtney Kardashian, 35, as he reportedly promised her he would continue his treatment until early January after she warned him she would fight his bid to gain joint custody of their children, Mason, five, Penelope, three, and Reign, 10 months, if he leaves the centre early. A source said previously: "Kourtney has set the terms that he is to stay in treatment for a total of 90 days, with the option to do outpatient after one month." Kourtney and her mother Kris Jenner, 60, have taken Mason, Penelope and Reign to visit Scott in the facility numerous amount of times throughout his stint and he's now determined to prove himself as a trusting father. An insider said: "Scott is actually taking this seriously. He told the them all that he will do whatever they want him to do so that he can remain a full-time father to his children."
