If you’ve been keeping up with the political soap opera that is the Trump family, you probably noticed the sudden shift in the scenery. One day Kimberly Guilfoyle is the main character, and the next, she's literally 5,000 miles away in Athens.
Enter Bettina Anderson.
She isn't just another name in the tabloid cycle; she is the woman who officially became Donald Trump Jr.’s girlfriend—and now, as of December 2025, his fiancée.
The transition was, well, kinda messy. For a long time, people were confused. Was he still with Kimberly? Who is this blonde socialite from Palm Beach? Why did Donald Trump himself announce the engagement at a White House Christmas party? Honestly, the timeline feels like it moves at light speed, but when you look at the details, it’s a classic case of out with the old "MAGA firebrand" and in with the "Palm Beach chic."
Who exactly is Bettina Anderson?
Bettina isn't a newcomer to the high-society world. She’s a third-generation Palm Beach resident. Her father, the late Harry Loy Anderson Jr., was a big deal in the banking world, becoming one of the youngest bank presidents in the country back in the day.
Basically, she grew up in the exact circle where the Trumps spend their winters.
She's 39. She’s a model. She’s a socialite. And she has a very specific vibe that is a total 180 from Kimberly Guilfoyle. While Kimberly was known for high-octane speeches and professional dresses, Bettina’s brand is more "stay-at-home mom" style—even though her Instagram bio famously joked about not having the husband, kids, or chores to go with it.

People in Florida have known her for years through her charity work with the Paradise Fund. But the rest of the world only started paying attention when she and Don Jr. were spotted kissing at her birthday party in September 2024.
The awkward transition from Kimberly Guilfoyle
You’ve got to feel for the logistics team on this one.
For nearly six years, Kimberly Guilfoyle was the face of the relationship. They were engaged. They bought a $9.7 million mansion together in Jupiter, Florida. Then, suddenly, rumors of a split started flying.
What’s wild is that Kimberly didn't just disappear. The Trump family basically gave her a promotion that served as a "polite" exit strategy. President Trump appointed her as the U.S. Ambassador to Greece.
Talk about a long-distance breakup.
While Kimberly was getting sworn in and moving into the Jefferson House in Athens, Don Jr. was already moving Bettina into his life. Sources close to the couple told The Daily Beast and Page Six that Don Jr. was looking for something more relaxed. He reportedly felt Kimberly was too "uptight" and focused on the media spotlight. Bettina, on the other hand, fits that casual, Florida-lifestyle aesthetic that he seems to prefer lately.

- The Overlap: Rumors suggest they were together for a few months before the public "official" split from Kimberly.
- The House: Interestingly, property records show Don Jr. and Kimberly still co-own that $9.7 million Jupiter home.
- The Reaction: Kimberly finally broke her silence in early 2026, telling the New York Times she’s "happy for Don" but admitted through sources that the engagement was "difficult" to see.
The White House Engagement: A 2026 Milestone
If you want to know how serious this is, just look at how the engagement went down. It wasn't a private dinner or a quiet beach walk. It happened at the White House.
On December 15, 2025, during a holiday reception, Donald Trump himself took the mic to congratulate his son. He actually praised Bettina’s "look," which sounds very on-brand for the President. Bettina followed up by calling Don Jr. the "love of her life" in front of a room full of GOP heavyweights.
It’s a "big win" for the end of the year, as Don Jr. put it.
Why this matters for the 2026 political landscape
Don Jr. isn't just a private citizen; he’s a massive part of the "America First" movement. His choice in a partner matters because it changes the "inner circle" dynamics.
Bettina is younger and has a massive social media presence that leans more into lifestyle and fashion than hard-hitting political commentary. This might be a tactical shift. It softens Don Jr.'s image a bit. Instead of two political powerhouses shouting from a podium, you have a high-society couple that looks like they belong on a yacht in Jupiter.
It’s also clear that the family has fully embraced her. Melania Trump was reportedly involved in the White House party planning where the news broke, and the President has given his "official" stamp of approval.

Common misconceptions about the relationship
A lot of people think Bettina is just a "rebound." But they’ve been together for over a year now. They survived a move, a presidential campaign, and the very public departure of an ex-fiancée.
Another big myth? That Kimberly and Bettina are at war.
Sure, it's awkward. They both showed up at the same inauguration parties in January 2025. But they’ve kept it civil in public. Kimberly is too busy navigating Greek energy deals and staring down Chinese influence in the Mediterranean to spend her time in a public catfight. She's actually become a bit of a sensation in Athens, being followed by paparazzi at 1:30 a.m. and appearing on the cover of Vogue Greece.
What to watch for next
Now that the ring is on the finger—and it's a massive diamond, by the way—everyone is waiting for the wedding date.
Will it be at Mar-a-Lago? Probably.
Will it be the biggest social event of 2026? Almost certainly.
If you’re trying to keep track of this family, keep your eyes on the Palm Beach social scene. Bettina isn't going anywhere. She’s already essentially living with Don Jr. at her townhouse, and his car is reportedly "always there."
Actionable Insights for Following the Story:
- Check Property Records: Keep an eye on that Jupiter mansion. If they sell it or if Don Jr. buys out Kimberly, that’s the final legal tie broken.
- Follow Diplomatic News: Kimberly’s success or failure in Greece will dictate how much she stays in the "Trump orbit" moving forward.
- Monitor the "Socialite" Shift: Watch how Don Jr.’s public tone changes. Bettina's influence seems to be moving him toward a slightly more "lifestyle-centric" brand compared to the high-voltage political era of 2020.
The era of Kimberly is over; the era of Bettina is just getting started.
