Kourtney Kardashian and Scott Disick are calling it quits.
After the release of compromising photos of Disick, the Keeping Up With the Kardashians stars broke up over the Fourth of July weekend, a source close to the couple tells ET. Disick has been spending an increasing amount of time with friends who "are not a good influence" on him and "not looking out for his best interests," the source adds.
Prior to their split, Disick was photographed getting touchy-feely with his ex-girlfriend, Chloe Bartoli, in Monte Carlo. Meanwhile, Kardashian spent her Fourth of July weekend in New York City with the couple's three children, Mason, 5, Penelope, 2, and Reign, six months.
This has been a tough few years for Disick. As documented on numerous occasions on E! reality shows, the 32-year-old struggles with substance abuse. This past March, he entered a rehab facility in Costa Rica.
Kardashian, 36, and Disick -- who have been dating since 2006 but never married -- also broke up in 2010 on Kourtney and Khloe Take Miami because of his alleged alcohol problem before reconciling.
That all being said, just six weeks ago Kardashian Instagrammed a sweet message to the father of her children on his birthday. "Happy happy birthday to my handsome, hilarious, sweet soul mate," she wrote.
Bartoli, the woman spotted with Disick in Monte Carlo, is a celebrity stylist along with her twin sister Marie-Lou. The siblings have styled the likes of Poppy Delevigne, Miranda Kerr and Selena Gomez.
