Mario Singer is the estranged husband of Ramona Singer, who we've seen on the Real Housewives of New York City for six seasons. As the show is now in its 7th season, we probably won't see much of Mario since Ramona announced their getting a divorce. After the previous season, reports came out that Mario had been cheating on Ramona with a socialite named Kasey Dexter. For our 5 Fast Facts on Dexter, click here. At the season 6 reunion show, Ramona said she refused to talk about their issues, said their marriage was fine and that she wouldn't discuss anything because of her daughter Avery. Unfortunately, Ramona says she gave Mario a second chance and he blew it. He was again pictured with Dexter out in public and Ramona released this statement: We were working very hard on our relationship and making great progress. It was really working well, and then I got the feeling that he started seeing [Kasey] again ... I would never reconcile with him. I believe in marriage, I gave him a second chance, and he betrayed me and our daughter. You just don't do that. Others who say they witnessed Mario cheating on his wife included reality stars Patti Stanger and Jill Zarin. On prior seasons of RHONY, Zarin did allude to Mario being a playboy. In late March 2015, Stanger opened up about witnessing Mario cheating to Us Weekly, saying: I saw the whole thing. I saw him pick the girl at a certain person's house — you probably know. It was a big dinner party, and we just came for dessert, and I watched this and I was, like, sober, and everybody else wasn't. And I went, 'What is going on here?' And then I was worried for Ramona. I was really worried for her. Because I saw shades of him trying — he had like a midlife crisis going on. And she doesn't deserve that. She's a great girl.
So, aside from the cheating, who is Mario Singer? Mario has a net worth of $18 million and he is a very successful business man. He is the Vice President of Classic Medallics (a manufacturer of awards, trophies, and religious jewelry) and Frederick Singer & Sons. When RHONY first started, we saw Mario's business briefly featured on the show. He also co-founded his wife Ramona's line True Faith Jewelry in 2005.
