If you’ve been keeping up with the political social circuit lately, you probably noticed the sudden, sharp pivot in Donald Trump Jr.’s personal life. One minute, he was the face of a high-octane power couple with Kimberly Guilfoyle, and the next, he was introducing a new face to the Mar-a-Lago inner circle.
People were confused. Honestly, it happened fast.
But Don Jrs new girlfriend—actually his fiancée now—is a name you’re going to hear a lot more of: Bettina Anderson. She isn't just a random face from the crowd. She is Palm Beach "royalty," a model, and a woman who has managed to do something very few people can. She won over the President of the United States.
The White House Reveal Everyone Missed
While the internet was busy speculating about where Kimberly Guilfoyle had disappeared to, the truth came out in the most "Trump" way possible. On December 15, 2025, during a White House Christmas party, President Donald Trump took the mic. He didn't just give a holiday greeting. He announced that his eldest son was engaged.
Don Jr. looked pretty thrilled. He joked about usually being the one "ranting and raving," but said he was at a loss for words.
"I want to thank Bettina for that one word: 'Yes,'" he told the crowd.
Bettina was right there beside him. She called it the "most unforgettable weekend" of her life. It was a massive moment that effectively ended months of "are they or aren't they" rumors that had been swirling around Palm Beach since late 2024.

Who Exactly Is Bettina Anderson?
Bettina isn't a newcomer to the high-life. Unlike the fiery, loud political energy of Guilfoyle, Anderson comes from a background of quiet, old-school Florida wealth. She’s 39, a twin, and the daughter of Harry Loy Anderson Jr. and Inger Anderson—big-deal philanthropists in the area.
She’s got the credentials to match the socialite tag:
- Education: She graduated from Columbia University in 2009 with a degree in Art History.
- Career: She’s worked as a model and appeared on covers like Quest magazine.
- Philanthropy: Along with her brothers, she co-founded The Paradise Fund, which does disaster relief.
Basically, she’s polished.
A source close to the family told People that the President is actually quite a fan. Apparently, he likes her "demeanor" and the way she looks. There’s a sense that the family felt Guilfoyle had become a bit of a "grandstander," while Bettina is more content to let the Trump name take the lead.
What Happened to Kimberly Guilfoyle?
The elephant in the room is obviously Kimberly. You don't just go from a multi-year engagement to a new fiancée without people asking questions.

The transition was... interesting.
Just as photos of Don Jr. and Bettina holding hands at a Palm Beach bar started hitting the tabloids in late 2024, the President nominated Guilfoyle to be the U.S. Ambassador to Greece. Talk about a "promotion-banishment."
She’s currently in Athens, living her best life at 1:30 a.m. pop concerts and overseeing drilling in the Ionian Sea. She even joked to the Greek President that she’s looking for a "new husband."
But the logistics are still messy.
Don Jr. and Kimberly still technically own a $9.7 million mansion together in Jupiter, Florida. Even though Don is "essentially living" at Bettina’s townhouse in Palm Beach now, that piece of real estate remains a lingering tie to his past relationship.
A Timeline of the Relationship
- March 2024: According to Bettina’s own Instagram, this is when they actually started dating.
- August 2024: The first "leak." They were spotted at brunch, and the Daily Mail went wild.
- December 2024: Hand-holding photos in Palm Beach basically confirmed the split with Guilfoyle was real.
- January 2025: Bettina attends the Inauguration as Don Jr.'s plus-one.
- December 2025: The official engagement announcement at the White House.
Why This Relationship Might Actually Last
A lot of people think these high-profile romances are just for show. But if you look at the shift in Don Jr.’s vibe, it’s different this time. He’s been seen at her townhouse constantly. His car is always there.
There’s a "natural fit" factor.
Bettina grew up in this world. She knows how to navigate the egos and the cameras without trying to steal the spotlight. For a guy who spends his days in the middle of political firestorms, having a partner who is "mellowed out" (as sources put it) might be exactly what he needs.
What Most People Get Wrong
The biggest misconception? That this was a snap decision.

It wasn't. They were quietly dating for nearly nine months before the public even caught a glimpse of them together. By the time the world knew about Don Jrs new girlfriend, she was already deeply embedded in the family structure.
She’s even tight with the grandkids. Kai Trump, Don’s daughter, has been seen in the same circles. It’s a full-on family integration.
Practical Insights for Following the Story
If you’re trying to keep up with where this is going, stop looking at the political rallies and start looking at the Palm Beach social calendar. Bettina is a staple at the amfAR Gala and local charity events.
Keep an eye on:
- Real Estate Filings: Watch for when that $9.7 million Jupiter mansion hits the market. That’ll be the final sign the Guilfoyle era is officially closed.
- Social Media: Bettina is active on Instagram, but she’s savvy. She posts the "vibe" without always posting the "man," which keeps the mystery alive.
- Official Events: Expect to see her at every major White House function through 2026.
This isn't just a rebound. This is a strategic and personal realignment of the Trump family’s social standing. Whether you’re a fan or a critic, there’s no denying that Bettina Anderson has successfully navigated one of the most difficult social climbs in America.
She’s here to stay.
To stay ahead of the curve, you should verify any new joint appearances at Mar-a-Lago events this season, as that’s where the real wedding planning details are likely to leak first. Check local Palm Beach society columns rather than just national news for the most accurate updates on their day-to-day life.
