Kourtney Kardashian and Scott Disick have split up, sources confirm.

According to a report by E! Online, the long-time couple has finally called it quits after being in a relationship for almost nine years and sharing three kids together.

The two were reported to have broken up over the weekend, last fourth of July. This is confirmed by the site's sources.

Adding to this, a statement was also released by the source, making the break up seem like it was Scott's fault.

"Kourtney has always taken Scott back and been by his side, but now with three kids it has gotten old," said the site's source. "Kourtney has to do what's best for the kids."

Another source also allegedly added a statement saying that Disick has been telling people that he is single. "Scott has been running around saying he's single," said the other source. "Kourtney dumped him after she saw the pics [in Monte Carlo] and he hasn't been home after a month-long party binge."

As previously reported, fans say that they already forsesaw the Kourtney Kardashian and Scott Disick split weeks ago, particularly when the photos showing Scott partying with his ex Chloe Bartoli surfaced on the internet.

The 36-year-old Kardashian has been reported by the site to have been extremely affected with the photos surfacing and finding out about Scott's alleged cheating.

A source for the site cited above said that she is only "putting on a brave face." Regardless, the person added that Kourtney is over the grieving stage. "She is over it," the source said. "She's fed up. It's humiliating and disrespectful. How much more is she supposed to take?"

"Scott does not seem to care about what he's doing," added the source. "He's clearly unraveling. He was a mess in NYC last month with the drinking and partying and he's been in a downward spiral ever since. He's been in trouble before, but this is on another level."

The Kourtney Kardashian and Scott Disick split comes months after the birth of their latest child, Reign. Aside from Reign, they both share two other children, Mason, five years old and Penelope, who is turning three on Wednesday.
