Scott Disick is allegedly planning to extend his rehab in order to have joint custody of his three children with his ex-girlfriend Kourtney Kardashian.

The reality star is said to have decided to remain in rehab for next 90 days since he was told by his Kardashian that joint-custody of their children will be denied if he left rehab earlier, according to The Mirror. Disick, who was addicted to alcohol checked into Cliffside rehab centre in Malibu on his own.

Disick entered the rehab around the same time Lamar Odom was checked into hospital after being found unconscious at a brothel in Nevada. It was reported earlier that Disick wasn't informed of Odom's condition since it might interfere with Disick's recovery at the Malibu rehab. However there were reports later claiming that Disick was much worried of Odom and he wished him well.

Scott Disick Will Remain In Rehab For Next Three Months

Earlier this week Kardashian visited Disick with her mom Kris Jenner and the couple's three children five-year-old Mason, Penelope, three, and Reign, 10 months at the rehab. During their visit Jenner and Kardashian have allegedly warned Disick that if he left rehab earlier he cannot have joint custody of his children.

"Kris and Kourtney have 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," noted a source, in a report by The Mirror.

"They told him that anything less is not acceptable and will prevent him from obtaining joint custody," the source added.
