Another day, another "Real Housewives" split.

"Real Housewives of New York City'' star Ramona Singer and her husband, Mario, have called it quits after 27 years of marriage, a source told E! News Monday.

Both spouses have reportedly moved on with other people; Mario, who's been the subject of cheating allegations for months, has reportedly been dating 27-year-old Kasey Dexter for roughly a year. Meanwhile, the New York Post reports that Ramona, 56, was spotted on a date with a “20-something-looking guy" recently.

News of the split comes just days after reports of a domestic dispute between the couple emerged. According to the Post, police were called to their hamptons home Friday night to break up a heated argument. Though Ramona initially accused her 60-year-old husband of choking her, no charges were pressed after the incident.

The couple, who have a daughter named Avery together, have yet to file for divorce.
