Los Angeles - Scott Disick checked into rehab in a bid to secure more access to his three children.
The 32-year-old reality TV star, who was dumped by Kourtney Kardashian in July after nine years together, reportedly decided to enroll in a drug and alcohol treatment program at the Cliffside Malibu in California after the Keeping Up with the Kardashians beauty, 36, informed him she doesn't think "he's fit to be a parent" to their three-year-old daughter, Penelope, and sons Mason, five, and Reign, 10 months, "without supervision".
A source said Scott checked into the treatment centre last weekend after admitting he has a problem, according to gossip website TMZ.com, and he has cut ties with the bad influences in his life.
Another source also claimed Scott decided to seek help for the fourth time after Kourtney issued him with an ultimatum and told PEOPLE.com: "He wants to make it stick this time because he has come close to losing everything."
The entrepreneur, whose life began to spiral out of control after the death of his parents in 2013 and early 2014, checked into the luxury facility shortly before Kourtney's brother-in-law Lamar Odom, who is still legally married to her sister Khloé Kardashian even though they both signed their divorce papers in July due to a backlog at the courthouse, was found unconscious at a brothel in Nevada on Tuesday.
While Lamar is fighting for his life in a Las Vegas hospital after an alleged overdose, Scott is not thought to be aware of his condition.
The insider said: "They don't want it to interfere with his progress."
