Divorcing ‘Real Housewife’ to keep her mansion

“Real Housewife of New York” Ramona Singer is keeping the Southampton mansion where she caught soon-to-be-ex-hubby Mario Singer allegedly cheating with much younger Kasey Dexter in January 2014.

The pinot grigio-swilling Bravo star, who filed for divorce last year, is apparently getting the 7,000-square-foot home in the settlement.

She reportedly bought the 1.4-acre spread, including a pool and tennis court, 20 years ago.

Mario will keep the former couple’s four-bedroom, 2,400-square-foot Upper East Side condo at 201 E. 80th St., but it is about to go on the market for $4.95 million with Douglas Elliman broker Lauren Muss, who did not return calls.
