Kourtney Kardashian and Younes Bendjima recently caused their fans to freak out when they unfollowed each other on Instagram earlier this week and now the reason behind their actions has been revealed. Turns out the couple did have a trouble in their relationship after the 24-year-old model got flirty with other models.

"Kourtney and Younes had their first huge fight over this past weekend. She heard some stuff about him getting flirty with other models and she called him out on it," a source tells HollywoodLife.com. "He got defensive and things escalated fast. A lot of things were said that they both eventually regretted, and they almost broke up over it."

But Younes isn't ready to lose Kourtney and he allegedly patched things up quickly. The so-called insider reveals, "He doesn't want to lose Kourtney." Adding that things are good again between the two, the source says, "He's being really sweet."

The source adds, though, that the issues between the pair are not completely solved. "But, it's hard not to wonder if this is the beginning of the end," the source adds. "Kourtney still has major jealousy issues and being with Younes triggers them at times."

"As much as she loves dating a hot male model Kourtney does tend to get threatened by all of the women he's surrounded with while he’s at work," the source admits. "It's hard on her at times and she can't help but want to give him a taste of what it's like for her. She may plan a sort of sexy photo shoot, something really steamy to make him see how it feels."

Scott Disick's cheating behavior with multiple women during his relationship with Kourtney reportedly still makes it hard for the mother of three to trust a man, even her current boyfriend.

Younes, meanwhile, has shown his love for his lady love by posting on Instagram Stories, "Morning beautiful," while tagging the reality TV star's Instagram handle.
