Kourtney Kardashian revealed that ex-boyfriend Scott Disick has "gone off-the-rails" in a sneak peak for the new episode of Keeping Up With The Kardashians.
Discussing how Scott reacted to news she's moved on with boyfriend, Younes Bendjima, the 38-year-old says she's received threats from Disick. "He's threatening me now, he goes, 'You better watch your back," Kourtney tells a concerned Kim and Khloé.
"This is not going to end well," responds Kim.
Scott and Kourtney started dating in 2006, despite remaining friendly they have not been a couple since 2015. Recently Disick, 35, went public with new girlfriend Sophia Richie, 19. Kourtney has also moved on stepping out with the 24-year-old model.
