You’ve probably seen the Google searches. People are obsessed. They want to know exactly how the numbers add up for the breakout star of Netflix’s Selling Sunset. Honestly, it’s not just about a birthdate. It’s about the fact that Mary Fitzgerald (now Mary Bonnet) seems to have lived about four different lifetimes in the span of one.
In the high-gloss, heavily filtered world of Los Angeles luxury real estate, age is often treated like a state secret. But Mary has always been surprisingly open about hers. She’s used it as a badge of honor, especially when navigating the "age gap" drama that fueled the earlier seasons of the show.

So, let's clear the air.
The Real Numbers: Mary Fitzgerald Age Explained
Mary Fitzgerald was born on July 29, 1980.
If you’re reading this in early 2026, that makes her 45 years old. She’ll be hitting the 46-mark this coming July.
Why does this matter? Well, in a cast often criticized for being "all filler and no substance," Mary’s age represents something specific: experience. She didn't just wake up and start selling $20 million mansions in the Hollywood Hills. She’s been in the game for nearly two decades. She started her real estate journey back in 2008, which, if you remember the global housing market at that time, was basically like trying to learn how to swim during a monsoon.
Most people would have quit. She didn’t.
The 13-Year Gap
You can’t talk about Mary's age without mentioning her husband, Romain Bonnet. When they first started dating, the internet basically had a collective meltdown. Romain was born in 1993, making him 13 years her junior.
People called him a "fame seeker." They called her a "cougar." It was pretty brutal, actually.
But here’s the thing—they’ve outlasted almost every other couple on the show. While other cast members were busy having televised weddings that ended in messy divorces (looking at you, Chrishell and Justin, or Christine and Christian), Mary and Romain have just... stayed together. They got married (twice, if you count the civil ceremony) and have been building a house-flipping business together.
The age gap didn't ruin them. If anything, Mary’s maturity seems to be the glue that holds their chaotic, reality-TV lives together.
From Teen Mom to Vice President
Mary’s timeline is genuinely impressive when you look at the hurdles. She became a mother at 16.
Think about that for a second. While most of us were worried about prom or getting a driver's license, she was raising her son, Austin. She’s spoken openly about how being a teen mom "shaped her life." It forced her to grow up fast.
She wasn't handed a trust fund. She worked. She moved from South Dakota to London, then to New York, and finally settled in LA. By the time she joined the Oppenheim Group in 2014, she already had a lifetime of "hustle" under her belt.
- 1996: Welcomed her son, Austin.
- 2008: Obtained her real estate license during the recession.
- 2014: Joined Jason and Brett Oppenheim at the O Group.
- 2019: Became a household name via Netflix.
- 2024: Released her memoir, Selling Sunshine.
Today, she’s the Vice President of the Oppenheim Group. She’s not just an agent; she’s management. She’s the one Jason leans on when the rest of the office is screaming at each other over a listing in Malibu.

The "Ageless" Aesthetic and Fertility Struggles
Of course, because it’s Selling Sunset, people love to dissect her appearance. It’s LA. Everyone looks 29 until they’re 60.
But Mary hasn't been shy about the realities of aging, especially regarding fertility. One of her most vulnerable storylines involved her and Romain trying to have a baby. They went through the grueling process of egg freezing and IVF.
It’s a conversation that resonates with a lot of women in their 40s. The biological clock is a real thing, even if you have a Netflix camera crew following you around. She didn't sugarcoat the disappointment or the physical toll it took.
She’s also been candid about her health. In 2023, she shared the heartbreaking news of a septic miscarriage. It was a rare moment of raw, unscripted pain in a show that often feels like a soap opera.
Why the Public is So Obsessed
Why do we care so much about Mary Fitzgerald's age?
It’s because she represents a specific type of success. She isn't an "influencer" who got lucky. She’s a professional who spent years in the trenches before the cameras arrived. In a culture that worships youth, Mary is proof that your 40s can actually be your "prime" years—both financially and personally.
She’s currently worth an estimated $2 to $3 million, though some reports suggest her social media income alone pushes that even higher. She’s closed over $140 million in career sales.
That’s not "teen mom" luck. That’s "45-year-old expert" energy.
Common Misconceptions
People often confuse her with other "Mary Fitzgeralds." There’s a famous author with the same name, and a politician in South Dakota.
But the Mary we know is the one navigating the "Bird Streets" and dealing with the ego of the Oppenheim brothers.
Another big misconception? That she’s "older than she looks." Actually, if you look at her early seasons compared to now, she’s barely changed. She attributes a lot of it to a strict skincare routine and, let’s be real, a very good injector. But she also stays incredibly active. You’ll often see her posting workouts that would make a 20-year-old sweat.
What You Can Learn from Mary’s Timeline
If you're looking at Mary’s life and wondering how she pulled it off, there are a few takeaways that don't involve selling a house for $30 million.
- Pivot when necessary. She went from nursing school to real estate. It’s never too late to change lanes.
- Ignore the "timeline" society sets. Having a kid at 16 didn't stop her from becoming a VP at 40.
- Invest in relationships that work, not ones that look good. Her marriage to Romain was mocked, but it’s the most stable one on the screen.
- Be transparent. People trust her because she doesn't hide her struggles—whether it's her age, her past, or her fertility.
Mary Fitzgerald's age is just a number, sure. But in her case, it's a number that tells a story of resilience. She’s the proof that you can start with nothing in South Dakota and end up running the most famous real estate office in the world.
If you want to keep up with her latest listings or her house-flipping projects with Romain, your best bet is following her Instagram. She’s remarkably active there, often sharing "behind the scenes" looks at the properties that don't always make it into the final edit of the show.
Next Steps: Check out Mary's 2024 memoir, Selling Sunshine, for a much deeper look into her early years as a single mother. You can also track her current luxury listings directly on the Oppenheim Group's official website to see the kind of volume she's moving in today's market.
