Scott Disick has asked Kourtney Kardashian, the mother of his three young children, for an open relationship.

According to Radar, the 32-year-old "Keeping Up With The Kardashians" star recently made his feelings known to the woman he has now be dating for nearly a decade.

"He's broken her heart by requesting an open relationship, which he claims is increasingly common and will only strengthen them," a source told the website.

The 36-year-old Kardashian's initial reaction is rumored to have been one of disgust. The source added she had been hoping Disick might finally be ready to set a wedding date and consider the possibility of the two having at least one more child together.

In recent months, Disick has also been rumored to have a severe drinking problem, which has reportedly even drawn the attentive concerns of newlyweds Kim Kardashian and Kanye West.

In Touch Weekly reports the two recently reached out to Disick to implore him to get help and seek treatment for his problem.

"The fact that he was too wasted to do his meet and greet in Montreal was the last straw," a source said of the June 6 event that was reported to have been ruined because Disick arrived too intoxicated to interact with fans. "They were already having a hard time overlooking his wild behavior while Kourtney is upset and home alone with the kids."

Reportedly, organizers were forced to refund all the money raised from the charity event and some deemed it a "complete disaster."

Disick was also recently rumored to have slept with another woman he was afraid he may have impregnated while he was on the road in Arizona. "Scott slept with her," a source told Hollywood Life. "She was really proud of herself for sleeping with him. She told everyone at work about it."

Kardashian and Disick are the parents of 5-year-old Mason, 2-year-old Penelope and 6-month-old Reign.
