After Kourtney got a new boyfriend, Scott spiralled into his old partying ways, in which Kourtney has always disapproved of.
It makes it harder that the pair share three kids, Mason, Penelope and Reign, and because of Scott's behaviour, he has had limited time with them.
Now, after America celebrated Father's Day, Kourtney subtly shaded the hell out of Scott on social media.
In the past, Kourtney has made beautiful posts for Scott on the special occasion, but this year she posted solely about her father Robert Kardashian.
"Blessed to call him my daddy. I couldn't have dreamed for any better. Happy Father's Day," she captioned the adorable snap.
Ouch.
Clearly things are realllll bad between the two, and we aren't sure if it's going to get better anytime soon tbh.
