Kourtney Kardashian Cries To Kim Over Scott's Cheating In Shocking 'KUTWK' Preview –– 'I Worked So Hard To Keep This Family Together'

In a shocking preview for Keeping Up With the Kardashians, Kourtney Kardashian shed tears after seeing photos of baby daddy Scott Disick getting too close to ex-girlfriend Chloe Bartoli.

"Scott is like on a crazy bender," Kourtney says, before a later scene in which she's weeping after images of Disick and Bartoli, a 25-year-old stylist, cuddling in France surfaced online.

The mother of Disick's three children -- Mason, 5, Penelope, 3 and 9-month old Reign -- tells sister Kim, "I worked so hard to keep this family together."

While Kourtney reacts with sorrow, her "Momager" Kris was flush with rage, calling the 32-year-old party boy "a piece of s**"t" in discovering the incriminating images, which would lead to a breakup shortly thereafter.

As RadarOnline.com readers know, it seems like Kourtney's been better off without Scott than vice versa, she's shed weight and shown off her revenge body, while staying on top of legal matters involving the custody of their kids; Scott continues to slog through a never-ending party and received the short end of the stick in their custody arrangement.

"Scott wants to be able to come and get them whenever he wants," insiders told RadarOnline.com, "and that is not something that Kourtney is willing to budge on."

Keeping Up With the Kardashians, now in its 11th season, airs Sundays at 8/7c on E!
