Bethenny Frankel And Ramona Singer In Talks To Appear On 'Millionaire Matchmaker'

During Bethenny Frankel’s 44th birthday party at Gilded Lily in New York on Sunday night, Singer was reportedly seen flirting with a much younger man. Later that evening, the reality star was said to have left the party with her mystery man in tow.

“Ramona was talking and dancing with a really hot guy who looked about 25 years old,” an onlooker told Radar Online on Nov. 10. “She was having a blast! They left together around midnight, [and] it looked like a hookup situation.”

Ramona Singer Says She And Avery Are "Embarrassed" For Mario After Highly-Publicized Affair

Around this time last year, reports began surfacing, claiming Singer's husband, Mario, had began an affair with socialite Kasey Dexter -- and that he allegedly got her pregnant (although that was never confirmed and Dexter never birthed a child). Months later, rumors hit the web again, claiming Singer confronted Mario and his mistress at their Hamptons home.

Even after Singer reportedly caught the pair together, she remained dedicated to her marriage, and tried to make her relationship with Mario last. 

Then, in July of this year, Mario went public with Dexter in New York, and Singer officially announced she was done with the marriage.

“Ramona is doing great,” said a friend. “She’s getting the last laugh!”

Ramona Singer and the rest of the cast of The Real Housewives of New York City, including LuAnn de Lesseps, Sonja Morgan, Heather Thomson and Carole Radziwill, will return to Bravo for a seventh season in 2015.
