The Cheating Scandal That Rocked RHONY: Who, When, and Why

The infidelity was a slow-burn storyline that eventually became the biggest drama of Ramona's tenure on the show. The details of the affair were shocking, involving a prolonged relationship that Mario initially denied.

1. The Initial Rumors and Fortune Teller's Prediction

Rumors of Mario’s wandering eye circulated among the cast for years, but the first major on-screen hint came during a cast trip to Morocco. A fortune teller explicitly told Ramona that Mario was going to cheat on her, an ominous prediction that Ramona initially dismissed but later came to define her marriage.

2. The Mistress Revealed: Kasey Dexter

Mario’s affair was with a woman named Kasey Dexter (sometimes referred to as Kyle Dexter), a personal trainer who split her time between New York City and the Hamptons. The relationship was not a one-time mistake; it was a long-term affair that continued even after the initial separation.

3. The Confrontation and Police Involvement

The situation escalated significantly in 2014. Ramona reportedly caught Mario and Kasey together at the couple’s Hamptons home. This confrontation was so intense that Ramona allegedly called the police, leading to a domestic incident report and confirming the end of their marriage.

4. Mario’s Post-Divorce Drama with Kasey

The drama didn't end with the divorce. Mario and Kasey continued their relationship for several years, but it was reportedly volatile. In a bizarre turn of events, their relationship ended with its own set of scandals, including reports of Mario sending Kasey eviction papers and even calling the police on her. There were also allegations that Kasey had cheated on Mario, mirroring the infidelity that brought down his marriage to Ramona.

5. The Financial and Emotional Toll

The divorce was finalized in 2016, but the emotional fallout was a major storyline for Ramona on RHONY for seasons afterward. She admitted to feeling that Mario "gave up on himself, on his business, and on us." The divorce settlement and the division of their assets, including their famous Hamptons estate, added a financial layer to the already devastating emotional toll.

Where Are They Now? Mario and Ramona's Current Relationship Status (2025)

Despite the infidelity and the messy, public divorce, the most surprising update for fans in late 2025 is the current status of Ramona and Mario's relationship.

Amicable Co-Parenting for Avery Singer

The couple has successfully transitioned from ex-spouses to friends and co-parents for their daughter, Avery Singer. Ramona has frequently shared that they are in a "much better place" now than they were during the height of the scandal. They prioritize their daughter and have been seen attending family events and even vacationing together as a family unit, a testament to their commitment to a peaceful post-divorce life.

Ramona Has Found Love Again

A significant update for Ramona is her focus on moving forward. After the tumultuous divorce, she confirmed that she has found love again with a new partner. She has expressed that her new relationship makes her "softer" and happier, a clear indication that she has emotionally recovered from the pain of Mario’s betrayal.

Mario and Kasey Dexter Split

The relationship between Mario Singer and his mistress, Kasey Dexter, eventually came to an end. After dating for over four years, the two split, confirming that the affair which destroyed Mario's marriage to Ramona did not lead to a lasting relationship for him. This breakup, combined with the other dramas in their relationship, provided a sense of closure for many RHONY fans.

In summary, while the question "Does Mario cheat on Ramona?" has a painful and public answer—yes, he cheated with Kasey Dexter, leading to their 2016 divorce—the story has evolved into a narrative of resilience.
