VIDEO : Scott Disick Is 'Seriously' Trying to Get Better This Stint in Rehab

Scott Disick is turning over a new leaf after all. The reality star, who ditched rehab only after one week earlier this year, is reportedly taking his treatment for drug and alcohol addiction ?really seriously? this time around. Since checking into Cliffside Malibu in California just three weeks ago, the 32-year-old is said to be sticking to his rehabilitation program. Disick has been doing so well that his ex-girlfriend, Kourtney Kardashian, has even allowed their children ? Mason, five; Penelope, four; and Reign, 10 months ? to visit him in the treatment facility. According recent reports, Disick is trying to sober up so Kardashian, 36, would allow him to see their kids after their split this July. This is Disick?s forth stint in rehab.
