Scott Disick Threatens Kourtney Kardashian For Dating Again On KUWTK

Scott Disick is green with envy, and it's not a good look.

According to E! News, the troubled reality star is having major issues with jealousy over his ex Kourtney Kardashian moving on with a new man. As seen in a sneak peek clip of Keeping Up With the Kardashians, released on Sunday, Oct. 22, 2017, things are about to take a turn for the dramatic.

"He's threatening me now," Kourtney told her shocked sisters, Khloé and Kim, in the preview. "He goes, 'You better watch your back.'"

"This is not going to end well," a concerned Kim replied.

As Us Weekly reported, Scott's threats also extended to Kourtney's model boyfriend, Younes Bendjima. The two have been dating since May 2017. "He's like, 'Your little friend is gonna get beat up,'" she revealed.

During the series' most recent episode, Scott's behavior had already begun to spiral. "I feel helpless because I don't always know what to do," Kourtney admitted, after receiving a phone call from a worried mutual friend (via Us Weekly). "I just, like, keep hearing that he's out of control. People have called me saying he's not gonna make it," she continued, before adding with a sigh, "He needs to fend for himself."

As Nicki Swift previously reported, Kardashian, 38, and Disick, 34, were together for nine years, but officially called it quits in July 2015. They share three young children together: Mason, 7, Penelope, 5, and Reign, 2. In September 2017, the former couple opened up about their complicated relationship on the 10th anniversary special of their hit TV show, when Kardashian announced that their longtime romance was permanently off. 

"The debauchery that has gone on has closed that door several billion times," she said, in reference to Disick's infamous partying ways and alcohol abuse. Scott was recently hospitalized and placed on psychiatric hold in August but is now reportedly "dedicated to getting better."

While we wait for this episode of KUWTK to air on Sunday, Oct. 29 at 9 p.m. on E!, read up on the messy truth of Kardashian and Disick's relationship.
