Reason Behind Scott Disick and Corey Gamble's Shocking Dinner Table Blowup Revealed

We finally know the cause of Scott Disick and Corey Gamble's dinner table screaming match.

"Keeping Up with the Kardashians" fans first saw a snippet of the fight between Kourtney Kardashian's baby daddy and Kris Jenner's boyfriend on the Season 17 supertease of the E! reality series -- and, thanks to a few new promos, we've got some context.

Looks like the heated situation exploded during a seemingly normal family dinner with Kris, Corey, Scott, Kourtney, Kim Kardashian and her best friend, Jonathan Cheban. In the preview that aired immediately following Sunday's episode, Kourtney revealed she had just parted ways with her nanny after 7-year-old daughter Penelope Disick scratched her face.

The preview gave no further details about the incident.

"I don't have a nanny anymore. Penelope scratched her," Kourt explained, putting her left hand up to her left eye to seemingly demonstrate what had happened.

"If P scratched me in my face, I'm whipping her ass!" Corey interjected, setting Scott all the way off.

"You would hit my daughter?!" he hurled across the table. "You just said, 'I would whoop her ass!'"

Corey fired back, "I'd whoop your ass!"

In another preview, Disick once again asked Gamble in disbelief, "My daughter?" He replied matter-of-factly, "Give her a spanking for sure."

"My little daughter?" Scott asked again.

"Whoopin' is a discipline!" Corey shouted, prompting Scott to bark back, "Don't ever talk about a child like that!"

"Motherf--ker, whatchu talkin' about?!" Gamble asked, as Disick replied, "Get the f--k outta here!"

In yet another promo, Scott was seen yelling, "Get the f--k out of here!" with Corey yelling back, "I'm not retracting a f--king word I said! I said what the f--k I said!"

Poor Kourtney said during a later confessional she was "shocked" by the whole evening.

According to previews, the episode will also include Kim telling Khloe Kardashian she "genuinely" needs to talk to a unnamed woman -- possibly Jordyn Woods -- and Khloe calling 9-1-1 after some kind of emergency involving Kris.

"Keeping Up with the Kardashians" airs Sundays at 9 p.m. on E!
