A source close to the reality star tells ET that Disick's rehab stint is not related to Lamar Odom's hospitalization.

Kourtney Kardashian is continuing to support her ex Scott Disick as he completes treatment at a drug and alcohol rehab center in Malibu, California, but the two aren’t getting back together anytime soon.

"The same still stands for Kourtney and Scott," a source close to Kourtney told ET on Thursday. "They are still broken up and there is no chance they will get back together. Kourtney is not interested in having any discussion about that right now, nor is she thinking about dating yet."

The Kardashian/Jenner clan have been through a lot recently, after Khloe Kardashian’s estranged husband Lamar Odom suffered a heart attack at a legal Nevada brothel on Oct. 13. Though Odom had allegedly been using drugs prior to his hospitalization, the source says that incident is not related to Disick’s rehab stay.

"Scott went into rehab the day before Lamar incident," the source said. "Scott did not go to rehab because of Lamar's overdose being a wake-up call or because it was an ultimatum from Kourtney. The two incidents are not connected."

While the source said they don’t know how long Disick will remain at the rehab center -- he is able to have cell phone access and come and go as he pleases -- they did refute rumors that circulated this week, notably that Kourtney was upset with her mother, Kris Jenner, for taking the former couple’s children to see Disick at the rehab center. Kris was spotted taking her grandchildren to Malibu over the weekend to see their father.

"It was Kourtney’s idea," the source said of the visit. "Kourtney would never want to keep the kids from their dad. That has always been her #1 rule. She does not want to see Scott at the moment, but she will never keep the kids away from him."

The source also shot down speculation that Kourtney planned to make Scott complete 90 days in treatment before he could see their kids: 5-year-old Mason, 3-year-old Penelope, and 10-month-old Reign.

"Kris was the best person to take the kids to see Scott," the source continued. "Kris still cares for Scott and wanted to make sure he was doing OK. She treated him like a son for 8 years…of course she still cares about him. He’ll always be the father of her three grandchildren."
