According to TMZ, Kourtney Kardashian dumped the father of her three children after his partying came in between them. "His partying lately has made her make this tough decision," one source tells the site.
Apparently, Scott hasn't been back to their shared home in Calabasas in over a month and Kourtney is tired of it. When Scott was in Monte Carlo, he was reportedly telling people that he was "newly single," so it doesn't seem that the photos themselves were necessarily a deal breaker because they happened after the fact.
Kourtney and Scott have been trying to work through his partying and we've seen him try various means to cut back on it over the years, but as TMZ's source explained, "Now, after 3 kids, it's gotten old and she has to do what's best for the kids."
E! News confirmed the split, with a source telling the site, Kourtney "is putting on a brave face but she is over it. She's fed up. It's humiliating and disrespectful. How much more is she supposed to take?"
Kourt and Scott were together for nine years and have three kids together - Mason (5), Penelope (3) and Reign (6 months).
