Mario Singer. If you followed The Real Housewives of New York City during the early years, that name probably triggers a very specific memory of a silver-haired businessman with a penchant for white wine and a slightly chaotic personal life. He was the husband of the "OG" Ramona Singer for over two decades. Then, everything imploded. It wasn't just a quiet divorce; it was a tabloid-fueled explosion involving infidelity, mistress rumors, and a very public fallout that played out across several seasons of Bravo TV.
People are still asking about the Mario Singer girlfriend situation because, frankly, his dating history since his 2014 split has been a rollercoaster. Some fans think he’s still with the woman who broke up his marriage. Others think he’s back with Ramona. The reality is actually a bit more complicated, involving long-term commitments, quiet breakups, and a surprising amount of "will-they-won't-they" with his ex-wife.
The Relationship That Started the Scandal: Kasey Dexter
You can't talk about Mario’s dating life without talking about Kasey Dexter. She was the catalyst. Back in 2014, Ramona famously caught Mario at their Hamptons home with Kasey, a younger fitness instructor. It was the "cheating scandal heard 'round the world"—or at least around the Upper East Side.
Most people assumed it was a mid-life crisis fling. It wasn't. Mario and Kasey actually stayed together for years after the divorce was finalized. They moved to Florida. They lived a relatively quiet life away from the cameras, though they occasionally popped up in paparazzi shots or social media posts. For a long time, if you were looking for the "Mario Singer girlfriend," Kasey was the only answer.
But then, the wheels fell off. In 2018, the relationship ended in a way that was arguably more dramatic than his divorce. There were reports of a messy blowout, accusations of spying, and even police involvement at their shared residence. Kasey eventually moved on, and Mario was suddenly a free agent in his 60s. He had to figure out what "dating" looked like after twenty-some years of marriage and a long-term rebound that ended in flames.

Is He Back With Ramona?
Here is where it gets weird. After the Kasey Dexter drama subsided, fans started seeing Mario back on Ramona’s Instagram. They were having dinner. They were quarantined together in Florida during the 2020 pandemic with their daughter, Avery.
They looked happy.
Naturally, the rumor mill went into overdrive. Was Ramona's former husband officially back in the picture? Was he the "new" Mario Singer girlfriend replacement? Not exactly. Both have been surprisingly candid about the fact that while they share a deep bond and a child, they aren't "together" in a romantic sense. Ramona has often described him as her "best friend" or "family," which is a massive pivot from the woman who once threw a wine glass at a reunion because she was so hurt by his actions.
They have a "modern family" vibe. They travel together. They support Avery. But as of late 2025 and moving into 2026, Mario is not officially back with Ramona. He’s navigating the Florida social scene, mostly keeping his romantic interests under wraps to avoid the media circus that followed him a decade ago.

Why We Are Still Obsessed With His Dating Life
It's about the narrative of redemption—or lack thereof. Mario was the villain of RHONY for a long time. Seeing who he dates is a way for fans to "check in" on whether he’s actually changed. When he was with Kasey, he was the guy who threw it all away. Now that he’s single (or dating privately), he’s seen more as a retired guy living his best life in Boca or Palm Beach.
The fascination also stems from the sheer longevity of the Singer brand. Even though they are divorced, people still view them as a unit. Any "Mario Singer girlfriend" has to live in the shadow of the Turtle Time queen herself. That’s a lot of pressure for any woman.
What the Social Evidence Suggests
If you look at his recent sightings, Mario is often surrounded by a rotating cast of friends in Florida. He hasn't debuted a "serious" partner on a red carpet or in a major magazine spread in years. He learned his lesson about publicizing his relationships.
- He spends the majority of his time in Florida.
- He is frequently seen with Avery Singer, who acts as his "main lady" at social events.
- He maintains a very cordial, almost flirty, friendship with Ramona.
- He avoids the Bravo spotlight whenever possible, despite the fans' hunger for a cameo.
The Reality of Post-Divorce Dating for 60-Somethings
Mario represents a very specific demographic: the wealthy, high-profile divorcee. For men in his position, the "girlfriend" title is often fluid. He has the resources to travel and socialize, which means he likely dates within a tight-knit circle of Florida socialites.

The struggle for him—and for anyone watching—is the baggage. You can't Google Mario without seeing the 2014 headlines. Any woman dating him has to be okay with the fact that his ex-wife is a literal television icon who still talks to him every single day. That takes a very specific type of personality. Someone low-key. Someone who doesn't want the "Real Housewives" fame.
Identifying the Patterns
If we look at his history, Mario tends to go for women who are active and social. Kasey was a fitness pro. Ramona was a business powerhouse. He isn't the type to date a wallflower. If there is a current "Mario Singer girlfriend" hiding in the wings, she’s likely someone he met at a tennis club or a high-end charity gala in Palm Beach.
Honestly, the most interesting thing about his current status is the silence. For a man whose private life was once public property, he has become remarkably good at staying under the radar. He’s living the "private life, happy life" mantra that so many celebrities pivot to after they’ve been burned by the tabloids.
Actionable Insights for Fans and Observers
If you're trying to keep tabs on Mario's status, don't look for a formal announcement. That's not how he operates anymore. Instead, watch the edges of the frame.
- Monitor Avery Singer’s Socials: Avery is the bridge. If Mario has a serious partner, she will eventually show up in the background of a family dinner or a holiday post. Avery is protective, so if a woman makes it onto her grid, it’s a big deal.
- Check the Palm Beach "Social Diaries": Local Florida blogs and society columns often catch him at events. He is a fixture in the South Florida social scene, and that’s where his romantic life actually lives—not on Bravo.
- Don't Believe the Reunion Rumors: Every few months, a gossip site claims Mario and Ramona are eloping. Take those with a grain of salt. They are "trauma-bonded" and share a daughter, but their romantic ship likely sailed when the divorce papers were signed.
- Acknowledge the Shift: Mario has moved from "TV Husband" to "Private Citizen." His dating life is no longer a plot point for a show, which means the information will be scarcer, but arguably more authentic when it does surface.
The "Mario Singer girlfriend" search usually leads back to a trail of old drama, but the current reality is a man who has learned the value of discretion. He isn't chasing the cameras anymore. He’s chasing a quiet retirement, a good game of tennis, and a relationship that doesn't end up as a Page Six headline. Whether that includes a permanent partner or a series of casual dates remains to be seen, but for now, his most stable relationship remains the one he has with his daughter and his surprisingly friendly ex-wife.
