A preview for an upcoming episode of Keeping Up With The Kardashians shows Kris delivering some harsh truths to Scott following his split from her daughter Kourtney Kardashian.
In the brief snippet of their conversation we say, Kris says bluntly: "You really f**ked up. You have to earn back trust you've lost."
Kourtney dumped Scott over the summer when pictures emerged of him looking cosy with another woman in Monte Carlo while she was home with the kids in LA.
It's alleged Kourtney, 36, had grown tired of Scott's constant partying and the pictures were the last straw, prompting her to pull the plug on their nine-year relationship.
They are parents to Mason, five, Penelope, three, and Reign, who turns one next month.
Keeping Up With The Kardashians airs Sunday nights on E!
