According to E! News, Keeping Up With The Kardashians star Kourtney broke up with Scott over the weekend due to his excessive partying and recent pictures of him hanging out with celebrity stylist and ex girlfriend Chloe Bartoli.
"Kourtney has always taken Scott back and been by his side, but now with three kids it has gotten old," said the source. "Kourtney has to do what's best for the kids.
"Scott has been running around saying he's single. Kourtney dumped him after she saw the pics [in Monte Carlo] and he hasn't been home after a month-long party binge."
Kourtney spent the Fourth of July bank holiday weekend with her kids, and she shared a photo to Instagram of herself happily smiling as she posed alongside daughter Penelope.
According to several US reports, Scott hasn't been home in a month.
Kourtney and Scott's nine-year relationship has been played out in the family's hit US reality TV show series. The show has also documented his partying lifestyle and the effect it hash had on his family, and in May, Scott entered rehab again at a facility in Costa Rica.
The couple have been dating since 2006 and have three children together: Five-year-old Mason, Penelope, almost 3 and six-month-old son Riegn Aston.
