The Ultimate Revenge! Kourtney Kardashian Plans To Leave Cheating Scott Disick Broke -- Why She's ‘Not Playing Fair Anymore’

Keeping up with the Kardashians reality star Kourtney Kardashian is no longer playing nice when it comes to her estranged ex Scott Disick!

RadarOnline.com has learned that the latest round of feuding was sparked by a preview for the upcoming season of KUWTK, when the mother of Mason, 5, Penelope, 3 and 9-month-old son Reign, was filmed crying to her sister  Kim Kardashian over Disick's cheating.

Disick was quick to hit back on Instagram, writing, "Stop talking peasant.”

Now, a source close to the Kardashian clan tells RadarOnline.com exclusively that it’s war!

“Scott told Kourtney that she needs to stop playing the ‘poor me’ game and when he said that to her, she absolutely blew up on him,” the source says.

“Since that episode was shot, things have obviously changed a lot between them. Although she was overly fair when it comes to their kids by giving him joint custody , she is not going to play fair anymore when it comes to their money.”

“Kourtney told him that she is going to leave him broke, and by the time she is done with him he will never get another job on TV again,” the insider tells Radar.

“He is already hurting financially since the breakup, but she wants to make sure he is in financial ruin,” adds the source.
