His partying had been a sore spot in their relationship for a long time and when he was photographed not only partying, but partying (and looking very cozy) with his ex, that seemed to be the last straw.
Most fans took Kourtney's side and seemed to lash out at Scott and his ex on social media, but in a surprising new Twitter post, it almost seems like Kourt is asking them to reserve their judgment...but about who, or what?
"There is only one lawgiver and judge, he who is able to save and to destroy. But who are you to judge your neighbor?" she tweeted, quoting James 4:12 from the Bible.
A lot of fans were confused, wondering if she was actually defending Scott (and the entire situation he found himself in) or if maybe people were saying mean stuff to HER and she was calling them out. Maybe it was just a general quote about not judging, although the timing seems a little coincidental.
Kourt hasn't elaborated, but either way, it's probably a good message for all the trolls out there.
