It isn't a secret. If you’ve turned on a television during a political convention or scrolled through a high-octane Instagram feed lately, you’ve seen her. The answer to who is Don Jr's girlfriend is Kimberly Guilfoyle, but that simple name doesn't really capture the sheer gravity she pulls in the current political landscape. She isn't just a "plus one" at Mar-a-Lago.
She’s a force.
Donald Trump Jr. and Kimberly Guilfoyle have been a pair since roughly 2018, surfacing shortly after Don Jr.’s split from his wife of 13 years, Vanessa Trump. It wasn't exactly a quiet debut. People talked. They always do. But what started as a headline in Page Six has morphed into one of the most significant partnerships in modern conservative circles.
From the DA's Office to the MAGA Inner Circle
Kimberly wasn't a stranger to the camera when she met Don Jr. In fact, she was a fixture. Before she was a fixture of the Trump campaign, she was a prosecutor in San Francisco and Los Angeles. She earned a reputation for being tough. Like, really tough. We're talking about a woman who co-prosecuted the high-profile "dog mauling" case in San Francisco—a trial that was essentially a media circus.
She's also got a past that makes for great trivia. She was once married to Gavin Newsom. Yes, that Gavin Newsom, the Democratic Governor of California. It feels like a lifetime ago, back when they were dubbed the "new Kennedys" by Harper’s Bazaar. How times change, right?
After the Newsom era and a second marriage to furniture heir Eric Villency, she pivoted hard into media. She spent years as a co-host on The Five on Fox News. That’s where she really honed that specific, high-energy delivery that defines her public speaking today. She knows how to hold a room. Whether you love her or find her volume a bit much, you can’t say she’s boring.
The Relationship Timeline: Beyond the Headlines
When people ask who is Don Jr's girlfriend, they’re usually looking for the "how did they meet" story. Honestly, they’ve known each other for years. They moved in the same social circles in New York for a decade before things turned romantic.

- 2018: The news breaks. They start appearing at events together shortly after Don Jr.’s divorce filing.
- 2020: She takes a massive role in the re-election campaign. Remember that speech at the RNC? The one that launched a thousand memes? It was loud. It was intense. It was pure Kimberly.
- 2021: They get engaged. It was actually a quiet engagement on New Year’s Eve, but the world didn't find out until a year later when she was spotted with a massive rock on her finger.
They bought a house in Jupiter, Florida. Not a small house. A $9.7 million mansion. It’s a move that signaled they were planting roots far away from the Manhattan elite that had, quite frankly, soured on the Trump brand. Florida is their turf now.
Why Kimberly Matters More Than a Typical "Girlfriend"
In most political families, the partner is a supporting character. They smile. They wave. They host luncheons. Kimberly Guilfoyle doesn't do "supporting character." She is a strategist and a fundraiser in her own right.
She headed the Trump Victory Finance Committee. Think about that for a second. She was responsible for the literal lifeblood of the campaign—the cash. Reports from the New York Times and other outlets have detailed how she brought a "corporate" yet aggressive style to the fundraising circuit. She isn't just standing next to Don Jr. on a stage; she’s often the one who built the stage.
Her influence on Don Jr. himself is also pretty evident. He’s leaned harder into his role as the "voice of the base." Together, they’ve become a sort of traveling roadshow for the "America First" movement. They do the podcasts. They do the rallies. They do the Rumble streams.
It’s a brand.
The Social Media Presence
If you follow her on Instagram, it’s a mix of high-glamour gowns and camo-clad hunting trips. It’s a weird juxtaposition, but it works for their audience. One day she’s at a gala at Mar-a-Lago, and the next she’s posting about "the best way to cook venison."

She’s basically the bridge between the old-school GOP donor class and the new-school MAGA populist movement.
Addressing the Rumors and the Criticism
Look, it hasn't all been smooth sailing. You can't be this loud and this public without catching heat. Critics point to her departure from Fox News, which was shrouded in various reports and "he-said-she-said" narratives. She’s faced scrutiny over her speaking fees and her role within the Trump Organization’s political arms.
Then there are the rumors. Every few months, the tabloids scream that there's "trouble in paradise" or that they’ve split. It’s a predictable cycle. Usually, these rumors are followed by a very pointed, very coordinated social media post showing them together on a boat or at a dinner, looking perfectly fine.
Is it all optics? Who knows. But in the world of high-stakes politics, optics are the reality.
The Engagement That Lasted Years
The engagement is a bit of a talking point. They’ve been "engaged" for a long time without a wedding date being made public. In some circles, that’s cause for gossip. But for them, it seems to be more about the partnership than the paperwork. They’re already living a combined life—merged finances, shared political goals, and a shared home.
They also manage a complex blended family. Don Jr. has five kids. Kimberly has a son, Ronan, from her marriage to Villency. Balancing six kids and a national political schedule isn't for the faint of heart. Honestly, it sounds exhausting.

What Most People Get Wrong About Her
People tend to caricature Kimberly Guilfoyle. They see the "The Best is Yet to Come!" speech and think she's just a shouting head on a screen. But if you look at her history, she’s a JD. She’s an attorney. She was a Deputy District Attorney. You don't get those jobs by just being "loud."
She understands the law, and more importantly, she understands the media. She knows exactly how to trigger a news cycle. When she says something provocative, she usually knows exactly how it’s going to land. It’s calculated.
Practical Takeaways: Understanding the Power Couple
If you’re trying to keep up with the Trump family's moves toward 2026 and beyond, you have to watch Kimberly as much as Don Jr.
- Follow the money: She remains a key gatekeeper for donors. If someone wants to get close to the Trump orbit, they often go through her or her team.
- Watch the media pivots: She’s been a pioneer in moving away from traditional cable news toward independent platforms. Her show on Rumble is a prime example of where she thinks the "real" audience lives now.
- The Newsom connection: Expect this to come up more often. As Gavin Newsom continues to be a national figure for the Democrats, the fact that Kimberly was once the First Lady of San Francisco is a weird, recurring "glitch in the matrix" that both sides love to weaponize.
What’s Next for the Couple?
There’s been plenty of talk about Don Jr. running for office himself. Maybe a Senate seat? Maybe something in Florida? If that happens, Kimberly won't just be the candidate's wife. She’ll be the campaign manager, the chief fundraiser, and the primary surrogate all rolled into one.
The question of who is Don Jr's girlfriend isn't just a gossip query anymore. It’s a question about the future of the Republican party. She’s woven into the fabric of the movement.
To really understand where the Trumps are going, you have to look at the people they choose to keep closest. Kimberly Guilfoyle isn't just "close." She’s right there in the cockpit.
If you want to stay updated on their specific political ventures, checking their filings with the FEC or following their verified accounts on Rumble provides a more accurate picture than the tabloids. Most of their "real" news is announced directly to their followers these days, bypassing the middleman entirely. This is the new playbook: direct access, high volume, and no apologies.
Keep an eye on the upcoming campaign cycles. You’ll see her name on the donor invites long before you see her on the stage. That’s where the real work happens.
Actionable Steps for Staying Informed
- Check the Filings: For those interested in the financial influence of the pair, the Federal Election Commission (FEC) website is a goldmine. Look for committees where she is listed as a chair or key fundraiser.
- Monitor Independent Media: Since leaving Fox, she focuses heavily on Rumble. Watching a few episodes of her show gives a better sense of her policy priorities than a 30-second clip on the evening news.
- Verify Tabloid Claims: When you see a "breakup" headline, cross-reference it with their public appearances. They are rarely apart for more than a few days due to their shared professional schedules.
