Ramona Singer Cheating Scandal: 'RHONY' Star's Reported Flame Has Ties To Her Husband's Mistress

Ramona Singer is reportedly seeing someone new, but the relationship hasn't come without complications.

According to a new report, the Real Housewives of New York City star is casually dating a man named Peter Guimaraes, who previously dated the mistress of Ramona's husband, Mario.

“Peter had actually met Kasey and began dating her before he met Ramona,” a source told Radar Online of Peter's relationship with New York City socialite, Kasey Dexter. “This actually is quite fascinating, in a perverse sort of way, and it’s better than any soap opera.”

Following the publication of Mario's ongoing affair with Kasey last year, he and Ramona came to blows and in late January, 2014, the reality star filed for divorce. Weeks later, according to the source, Ramona met Peter at his New York eatery, Alfredo 100, and sparks flew.

“I don’t think either of them knows that Peter even knew the other one, let alone that he’s been seeing them both," the source said. "Obviously he has a bit of the playboy—and the cad—in him.”

Just one month ago, it was reported that Ramona was considering taking Mario back, following his cheating scandal, but judging by this new report, that may not be the case.

Since Ramona's divorce filing, she and Mario have been spotted together more than once and during an interview with Bethenny Frankel, she seemed to hint that she and Mario's marriage may not be over, telling her former co-star, "Nothing is set in stone," when it came to the divorce.
