The verbal blow-up (which went down in public at a restaurant) began when Kourtney revealed they’d parted ways with their nanny after their seven-year-old daughter, Penelope, scratched her face. For some reason, Corey had a really strong reaction to the debacle and later suggested he would “whoop Penelope’s ass” and “give her a spanking” if she ever hurt him.  

Although Kris tried to diffuse the situation, claiming that despite his aggressive remarks he’d never actually hurt Penelope, Kourtney had already made up her mind, admitting“He will never be with my kids alone and if he does that in front of any of us there will be a f**king issue!”
