Kourtney Kardashian and Scott Disick call it quits

Kourtney Kardashian is putting the kibosh on her relationship with Scott Disick!

The former couple, who share three children together, broke up over the Fourth of July holiday weekend, sources confirmed to E! News.

The split isn't a huge surprise. Late last week, Disick, 32, was spotted canoodling with a mystery woman in Monte Carlo. He appeared to be extremely cozy with the woman and was photographed rubbing her back and hanging out poolside with her. Kardashian, 36, was reportedly furious over his antics abroad.

"Scott has been running around saying he's single," a source told E!. "Kourtney dumped him after she saw the pics [in Monte Carlo] and he hasn't been home after a month-long party binge."

Neither Disick or Kardashian have released a formal comment about their split.

The longtime lovebirds have been dating since 2006 and have taken a break before. In 2010, while Kourtney was filming "Kourtney & Kim Take Miami" the pair took a break after Scott struggled with an alcohol problem. The duo reconciled after Scott attended counseling. Since his treatment, Scott has been in and out of rehab, most recently seeking treatment in Costa Rica in March 2015.

Kardashian has been home in California taking care of their three kiddos, Mason, 5, Penelope, 3, and Reign, 6 months.
