For years, those who follow the reality show "Keeping up with the Kardashians" have protested Scott Disick's relationship with Kourtney Kardashian, with many people (including Kourtney's own superstar sister, Kim) telling her she could do better than him - could things change after the latest Scott Disick rehab?

Last October, the reality star that was Kourtney's long-lasting love for years checked himself into a Malibu facility for treatment, the fourth time he's gone through this procedure, and the past weekend saw his ex visiting him for the first time and bringing their oldest two children together, prompting rumors that Scott Disick's rehab stint might ultimately save their relationship.

According to People Magazine, Kourtney joined 5 year-old Mason and 3 year-old Penelope in their latest visit to Scott Disick in rehab at Cliffside Malibu last Sunday, joined by Kourtney's youngest sister, 18 year-old social media queen Kylie Jenner.

"Scott was really happy to see the kids and was very loving with them," a source close to Scott Disick on rehab told Us Weekly regarding the recent visit, which reportedly went on for about two hours. "He visited with them inside for awhile and then took them outside to admire the view from the balcony."

It seems like, as Kourtney and the children visited Disick, the former couple seemed to be on amicable terms, while the oldest Kardashian sister stood back and let her ex play with their kids.

According to Life and Style Magazine, Scott Disick's rehab time has made him think back on what he's lost in the past few months, and part of his process of recovery includes writing a letter to everyone he's hurt with his own issues - and that includes Kourtney, to whom he reportedly wrote everything "she needed to hear and it really came from his heart."

It's unclear whether the two will get back together after Scott Disick's rehab, but he certainly seems to be in the right track towards recovery.
