Bettina Anderson was used to life in the public eye for years, but she quickly found herself in a new kind of spotlight. In late 2024, reports surfaced about her relationship with Donald Trump Jr., who had been dating ex-fiancée Kimberly Guilfoyle since 2018.
After more than a year together, Don Jr. proposed to Bettina in December 2025 during the White House Christmas party. Since then, Bettina has continued gaining public attention as she joins the Trump family’s inner circle, attends major political events and has married Don Jr. during a private Bahamas wedding celebration over Memorial Day weekend 2026.

Per Bettina’s profile on The Paradise Fund’s website, she “loves being in the water and, as a licensed rebreather tech diver, she has a unique and special lens for witnessing the impact that over-development is having on our natural waters and marine wildlife.”
Bettina is also involved in the fashion world. In 2022, she spoke with Fashion Week Daily about the Project Paradise Film Fund Initiative, which she said she was “so proud” to be a part of.
“One of the greatest focuses of my life is how I can be of service to others and a be steward of the environment,” Bettina said at the time.

Bettina is reportedly 39 years old, born in December 1986. Don Jr., who is 48, was born on December 31, 2025. The couple has a nine-year age gap.

When Did Bettina Start Dating Donald Trump Jr.?
Betting and Don Jr. started dating in mid-2024, according to People. A source told the publication in December that the couple have “been dating for about six months” — even though Don Jr. was still in a relationship with Kimberly. The insider further alleged that Don “took [Bettina] on a trip to Alaska and introduced her around as his girlfriend when he was still very much with Kim.”
“For the most part Kim has looked the other way because she loves the power and lifestyle,” the source claimed.
Don Jr. and Kimberly avoided publicly commenting on the reports about their romance, but they confirmed their engagement in December 2025. Don’s father, Donald Trump, nominated Kimberly to be the next ambassador to Greece.
