Kourtney Kardashian is allegedly angry with her mother for siding with Scott Disick amid his rehab following the split.

Scott Disick's downward spiral has been well chronicled as he was snapped hooking up with an ex and partying non-stop. His behavior-capped by his decision to go incommunicado from Kourtney Kardashian for about a month-led to the split.

Reportedly, there's a lot of bad blood between the former couple, even if they have been snapped a couple of times taking their kids out for a family day.

"Now that Scott Disick is finally taking rehab seriously, he wants Kourtney Kardashian back," said CDL. "According to multiple reports, Scott has been blowing Kourtney up, asking his former longtime girlfriend if she will just consider giving him another chance."

The "KUWTK" star, meanwhile, is not in a forgiving mood and that's why Kourtney Kardashian is allegedly furious with Kris Jenner for siding with Scott Disick.

"Some believe that Kris Jenner is being greedy," CDL added. "It is a pretty good possibility that Jenner is just a great business manager and knows that cutting Scott loose from "Keeping Up With The Kardashians" is a horrible move for the show."

Us Weekly reported that the "KUWTK" star is only civil towards Scott Disick for the sake of their three kids, Mason, 5, Penelope, 3, and Reign, 9 months, after the split.

"They're amicable for their kids but Kourtney is officially done," the report said. "It's hard for her, but she's moving in the right direction,"

"Scott misses his family, but it's not enough to motivate him to change," the source claimed. "He doesn't have the constitution to cure himself of his issues."

Earlier this month, Scott Disick was pictured with a mystery blonde who reportedly stayed in his hotel until morning. The news report came on the heels of the announcement that the self-confessed party-organizer extraordinaire is going to rehab to address his own issues.
