American reality television star Kourtney Kardashian and longtime boyfriend Scott Disick have reportedly split.
According to E! News, the pair, who have three children together, ended their relationship over the 4 July holiday weekend.
The news comes after Disick was pictured getting close with his alleged former girlfriend Chloe Bartoli.
"Kourtney has always taken Scott back and been by his side, but now with three kids it has gotten old," a source told the website. "Kourtney has to do what's best for the kids."
"Scott has been running around saying he's single," the insider added. "Kourtney dumped him after she saw the pics [in Monte Carlo] and he hasn't been home after a month-long party binge."
Another source revealed that Disick has been spending an increasing amount of time with friends who "are not good influence" on him and "not looking out for his best interests".
Kim Kardashian's sister and Disick have been dating since 2006 and are parents to Mason, Penelope and Reign.
It was previously reported that Kourtney was worried Disick would leave her before the birth of their third child.
Disick expressed shock and anger when Kourtney revealed that she was pregnant for the third time in June, and it was aired on the family reality TV show Keeping Up With The Kardashians. He admitted he was not ready for a third arrival.
