Scott Disick & Kourtney Kardashian Split: Disick Accuses Kourtney of Cheating, Suspects He Is Not Reign's Dad

When Kourtney Kardashian ended her nine-year relationship with Scott Disick, things between the two ex-lovers just fell apart. The pair is obviously not in friendly terms.

Kourtney decided to call it quits after enduring Scott's heavy drinking problems and hard-partying when photos of Disick circulated getting too close for comfort with ex-girlfriend, stylist Chloe Bartoli. Following the breakup, a woman was spotted carrying a load of Scott's belongings out of the mansion the ex-lovers used to share.

The incident occurred when Kourtney celebrated their daughter Penelope's third birthday at Disneyland with Kim Kardashian and her two-year-old daughter North West. At the time Disick was reportedly in Florida. The items were unloaded into the $3.5 million Beverly Hills home that Disick purchased last December.

Then, there were reports claiming that Kris Jenner might cut the father-of-three out of their reality show "Keeping Up With The Kardashian," which did not threaten Scott at all, as he will still be earning $4,000,000 a year from the show as stated in his contract as long as he cooperates with the producers even if they edit him out, TMZ reports.

The recent reports about the pair suggest that Disick is accusing Kourtney of infidelity. In fact, he is suspecting that he is not the father of their youngest son, Reign, OK! Magazine reports. "There's been buzz in their circle that Kourtney cheated and Reign might not be Scott's. He flipped when he heard it, and he's been off the rails ever since," an insider told the publication.

This incident might explain why Disick is often seen out with kids Mason and Penelope but has yet to be photographed with Reign. Disick was obviously upset with Kourtney's cheating issue. "He's behaving strangely. There's definitely something going on," the source added.

According to the report, this is not the first time Kourtney was accused of cheating. In 2013, she was linked to model Michael Girgenti. Girgenti was adamant that he slept with Kourtney when she was on a break from Scott and that he fathered Mason.

Kourtney proved that the reports were false after releasing a paternity test. However, the said incident seemed to damage their relationship. It "planted a seed in Scott's mind, and he's never totally believed that Kourtney wasn't playing around behind his back," disclosed the insider.

Although Kourtney has not slept with another man it does not guarantee that she's not at fault in terms of their parenting issues, "Scott's not the only one who was up to no good. She's definitely acting as though Reign is hers, not theirs. It's just a really sad situation for everyone," added the source.
