A few weeks after their luxurious island wedding in the Bahamas, Donald Trump Jr. and Bettina Anderson have bought a plot of land in West Palm Beach, Fla., Page Six has learned.

Sources say the newlyweds picked up a double lot in the Prospect Park neighborhood and plan to build an eight-bedroom home for their family.

Trump has five kids with his first wife, Vanessa, and sources have recently told Page Six that he and Anderson want to have more soon.

Sources note it will have plenty of room for entertaining and hosting political fund-raisers.

Still, Palm Beach snobs may raise their eyebrows at the plans. West Palm, which is on the mainland, is considered a little downmarket compared to Palm Beach proper, which is a barrier island off the coast.

His father, President Donald Trump, of course, owns the famous Mar-a-Lago club on the island.

Sister Ivanka, meanwhile, has a $24 million home with husband Jared Kushner down the coast on Indian Creek Island, also known as the Billionaire Bunker, a little north of Miami.

Brother Eric and his wife, Lara, have a home in Jupiter, to the north.

Anderson is a dyed-in-the-wool Palm Beacher. She was born in the city and attended the Palm Beach Day school.

Don Jr. and his former fiancée, US Ambassador to Greece Kimberly Guilfoyle, also lived in Jupiter during their relationship.

They bought their place for $9.7 million in 2021, and The Post’s Jennifer Gould reported in January that they had listed it for $30 million.

Don Jr. and Anderson married in an intimate ceremony on a private island in the Bahamas on May 23, in front of approximately 40 people, including his children and siblings. The president did not attend.

Anderson’s family and a few very close friends of the bride were also present.

Reps didn’t comment.
