Disick, 32, and Kardashian, 36, have three children together: Mason, 5, Penelope, 3, and Reign, 6 months.
The two have long butted heads on their reality shows, and previously split in 2010 when Kardashian accused Disick of having an alcohol addiction during filming for Kourtney and Kim Take Miami.
The couple attended counseling, and Disick temporarily gave up drinking.
Disick again entered counseling briefly last year during Kourtney & Khloé Take the Hamptons, and again this past March.
Kardashian was spotted filming with her sisters in Los Angeles last week and posted this smiling picture on Instagram on the 4th of July with daughter Penelope.
BuzzFeed has reached out to a representative for the Kardashians for comment.
