Kourtney Kardashian and Scott Disick are locked in a heated battle against each other — about their three kids!

The 37-year-old Keeping Up With The Kardashians star was spotted looking worn down from her relationship drama with her baby daddy.

As Star reported, Kourtney recently gave Scott an ultimatum — to ditch his boozy benders and start acting like a dad! The oldest KUWTK sister threatened that if he didn’t pull himself together, she was planning on asking for full custody of their children — Mason, 7, Penelope, 4, and Reign, 2.

But according to what insiders told RadarOnline.com, Scott isn’t answering to her demands.

“Kourtney and Scott had it out after she told him she was going after custody, and he told her that there is no way in hell that he would allow that to happen,” a source told Radar. “He told her that she was a drunk, too, and the only difference between them is that she hides it well!

“He doesn’t think the kids are in any danger. He told her she can f**k off!” the insider said.

As Star readers know, Scott and Kourtney broke up in 2015 after nearly 10 years ago. The troubled pair have tried multiple times to rekindle their romance, but Scott hasn’t been able to leave his wild partying behind.
