When you see Kimberly Guilfoyle on stage or on your screen, she's usually in full "political powerhouse" mode. But behind the high-energy speeches and the glare of the cable news cycle, there’s a side of her life that stays relatively tucked away from the headlines. I'm talking about her son. If you've ever scrolled through her Instagram and caught a glimpse of a tall, athletic young man she calls "RoDog," you've seen Ronan Anthony Villency.
He's not a "Trump" by blood, despite how often he’s seen with that family. He’s the product of a completely different era of Guilfoyle’s life. Honestly, his story is pretty fascinating because he sits at the intersection of two very different New York worlds: high-end interior design and high-stakes national politics.
Who Is Kimberly Guilfoyle's Son?
Basically, Ronan Anthony Villency is the only child of Kimberly Guilfoyle and her second husband, Eric Villency. He was born on October 4, 2006, in New York City. As of early 2026, he’s 19 years old.

While his mom is famous for her roles at Fox News and her political activism, his father comes from a legendary furniture dynasty. Eric Villency is the CEO of the Villency Design Group and the grandson of Maurice Villency, a name that’s basically synonymous with luxury furniture in New York.
Ronan’s parents married in 2006 in a beautiful ceremony in Barbados. It was a bit of a whirlwind. They had Ronan just a few months later. But by 2009, the marriage was over. Despite the divorce when Ronan was just three, the two have reportedly been masters of the "friendly exes" dynamic. You’ll still see them in photos together for Ronan’s big milestones, like his high school prom in 2024.
Growing Up in the Spotlight
It’s gotta be weird growing up when your mom is one of the most recognizable faces in conservative media. Ronan has spent his teenage years navigating a very public life while trying to maintain his own identity. He attended a prestigious private school in Manhattan. Interestingly, that’s actually how the whole Guilfoyle-Trump connection started.
Guilfoyle and Donald Trump Jr. weren't always a couple; they were actually "parent friends" first. Ronan went to the same school as Don Jr.'s eldest daughter, Kai Trump. The two families were already in the same social circles long before any romantic sparks flew between the parents in 2018.
- Full Name: Ronan Anthony Villency
- Birth Date: October 4, 2006
- Parents: Kimberly Guilfoyle and Eric Villency
- Education: High school graduate (Class of 2024), now in college
- Interests: Football, fishing, wakeboarding, and politics
The "RoDog" Persona and Personal Life
Guilfoyle is clearly obsessed with her son in the best way possible. She frequently calls him her "best boy" and "the most beautiful blessing." But what is he actually like?
From what we can gather from social media snippets, he’s a massive sports fan. We’re talking American football, fishing trips, and wakeboarding. He’s got that classic "outdoorsy" vibe. He isn't just a kid who sits in the background of political rallies; he seems to genuinely enjoy being active.
He’s also notably tall—often towering over his mother in photos. He has his father’s frame but definitely has his mother’s features. He doesn't seem to have a public, verified Instagram of his own (or if he does, it’s locked down tight), which is probably a smart move given how polarizing his mom’s career can be.
His Role in the "Blended" Trump Family
Since 2018, Ronan has basically been part of the Trump inner circle. When Kimberly and Don Jr. moved to Florida in 2021, buying a massive estate in Jupiter, it was all about creating a space for their "blended" family. That includes Don Jr.’s five kids (Kai, Donald III, Tristan, Spencer, and Chloe) and Ronan.
You’ve probably seen him at the big events:

- The 2024 Republican National Convention (RNC) in Milwaukee.
- New Year’s Eve parties at Mar-a-Lago.
- Various campaign trail stops where he supports his mother.
Even though he isn't a Trump, he seems to have a solid bond with Don Jr. and the rest of the crew. Kimberly has posted photos of Ronan and Don Jr. together, often praising how they get along. It’s a complicated family tree, for sure, but they seem to make it work.
What's Next for Ronan Villency?
Now that he's 19, the big question is whether he’ll follow his mom into politics or his dad into the world of design and business.
In 2024, Kimberly shared photos of his high school prom and graduation, getting all emotional about him "embarking on milestones with confidence." While the specific college he’s attending hasn't been blasted all over the news (likely for privacy and security reasons), he is currently in the thick of his university years.
Some people think he’s a shoo-in for a political career. He certainly has the "look" and the exposure. He’s comfortable on stage and has been around world leaders since he was a kid. Others think he might lean into the Villency business side—after all, he’s the heir to a design legacy.
Why People Get Him Confused
A lot of folks assume Ronan is Don Jr.'s son or that he’s related to Gavin Newsom (Kimberly’s first husband). Just to set the record straight:
- Gavin Newsom: Married Kimberly from 2001 to 2006. They had no children.
- Eric Villency: Married Kimberly from 2006 to 2009. He is Ronan's father.
- Donald Trump Jr.: Engaged to Kimberly. He is a father figure to Ronan, but not his biological dad.
It's easy to see why people get muddled. Kimberly’s life has been a series of very high-profile chapters. Ronan is the constant through all of it.
If you’re looking to keep up with what Ronan is doing, your best bet is actually following Kimberly’s social channels. She is the primary source of any updates, usually posting for his birthday in October or during major holidays. Given his age and the current political climate, don't expect him to launch a public-facing career just yet. He seems content to stay in the "student" phase of life while supporting his family from the sidelines.
For those following the family’s move to Florida or their political trajectories in 2026, keep an eye on those Mar-a-Lago holiday photos. That's usually where you'll catch a glimpse of how the next generation is shaping up.
Actionable Next Steps:
- Verify the Timeline: If you’re researching the family history, remember that the move to Jupiter, Florida, in 2021 was the major turning point for the blended family dynamic.
- Look for Design Connections: To understand the "other side" of Ronan's heritage, look into the Villency Design Group’s current projects, which offer a glimpse into his father’s professional world.
- Monitor Official Briefings: Since Kimberly Guilfoyle was nominated as US Ambassador to Greece in late 2024, any official family travel or residency changes in 2025-2026 might involve Ronan during his college breaks.
