We thought we'd give you an update on Kourtney and Scott's messy split, so here ya go!

It was reported yesterday that Kourtney Kardashian dumped Scott Disick after nine years together, and now the nasty details are pouring in. The drama began when the father-of-three was photographed getting way too cozy with his ex Chloe Bartoli in Monte Carlo last week, and while we assumed the couple had called it quits before that trip, they actually hadn't. The eldest of the Kardashian clan was apparently blindsided by the cheating photos!

TMZ reports the reality star had agreed to stick by LD while he battled his susbstance abuse issues, but she never thought he was being unfaithful. Once she saw the tell-tale pics, she was allegedly floored, and now worries about how many other women are waiting in the wings to tell their story about hooking up with her boyfriend!

The E! star has put up with a lot in their relationship, but she ultimately decided to pull the plug on their partnership for the well-being of their children Mason, Penelope, and Reign. "She was over dealing with his constant lies and addictions. It was becoming a poor environment for the kids to be raised in and she refused to let that be the case," a source dished to People. "Kourtney is willing to sacrifice her relationship with Scott in order to keep [her kids] safe. Her children are her first priority. She needs to protect herself and her family, so she knows this is the right decision," the source added. Sounds pretty final to us!

His baby mama has reportedly changed the locks on the family's Calabasas mansion, but the party boy won't be homeless! Back in December 2014, he was the sole buyer of a bachelor pad in the Beverly Park area of L.A. "Kourtney does not feel safe because of Scott’s current condition and she is having him locked out of the property. He is obviously hurting a lot but the fact that he is showing such blatant disregard for her feelings and for the well-being of their kids has really pissed her off," an insider revealed to Radar .

It remains to be seen what happens next! Among television's most famous family's concerns? That Scott could accidentally overdose or expose all the family secrets for money!

And they thought Kris Humphries was a problem!
