Mario Who? 'Real Housewives Of New York' Star Ramona Singer Dating Hunky New Millionaire Business Man

Ramona Singer has said she's been "having fun" dating, but RadarOnline can exclusively reveal that the Real Housewives of New York City star has found a man! Sources close to the star confirm she is dating Manhattan business mogul Thomas D'Agostino Jr.

A source close to Singer tells RadarOnline.com that Singer and D'Agostino "have been seeing each other for a few months." However, the Ramona Coaster is not looking to settle down, and the pair is "not dating exclusively at the moment," the insider tells RadarOnline.com.

D'Agostino, who runs in the same social circle as Singer, 58, and her Housewives pals, is the CEO of Smart Source, LLC and owns properties all over Manhattan.

In addition to running his printing business which draws in revenues in excess of $50 million, the mogul, 48, has been taking Singer out on dinner dates and "leads an active lifestyle" full of golf, skiing and sailing, the source says.

Singer, who split from cheating husband Mario in 2014, was most recently linked to a man much younger than her ex-husband.

RadarOnline revealed back in April that Singer was dating New York businessman Michael Alexander when she brought him to a party for the season six RHONY party at her restaurant, AOA.

She filed for divorce last year after catching her husband of 27 years cheating with his mistress, Kasey Dexter, 31. The pair have still not finalized their divorce as they continue to divide their assets.
