Kourtney Kardashian and Scott Disick have reportedly called it quits.

According to TMZ, the couple of nine years has broken up, with sources blaming the split on Disick's love of partying.

The "Keeping Up With The Kardashians" couple have been together since 2006, and have three children together -- Mason, Penelope and Reign. Their relationship has been on and off, as played out in the family's reality TV show series. The show has also dealt with Disick's problem with alcohol.

Kourtney spent the Fourth of July weekend with her kids, posing for a patriotic picture with Penelope.

Rumors, however, suggest that Scott hadn't been home in a month, and that he's been canoodling with celeb stylist Chloe Bartoli this weekend.
