Supermodel Alessandra Ambrosio is engaged to jewelry designer Buck Palmer after a nearly two-year relationship. Ambrosio, 45, confirmed the engagement via a joint Instagram post with Palmer, 44, writing, "I’d choose you in this life and every life. Here’s to forever, my love." The proposal took place on a beach in Indonesia, where Ambrosio was seen in a bikini as Palmer knelt on the sand. She displayed a new diamond ring as the couple embraced.
Ambrosio and Palmer were first romantically linked in 2024 at a party during Miami's Art Basel. Sources at the time indicated that Ambrosio hoped to spend her life with Palmer due to their deep connection. In 2025, Ambrosio told Us Weekly that she and Palmer connect through their shared "passion for life."
Earlier this year, engagement rumors circulated after Ambrosio shared Instagram photos featuring a gold band on her ring finger. A source told The Daily Mail in April that if Ambrosio was engaged, she had not yet informed her friends, but that the couple appeared serious and in love, suggesting the ring could be a significant hint. It was also noted that Palmer, as a jewelry designer, likely created the ring.
Ambrosio was previously engaged to Jamie Mazur. The couple, who share daughter Anja, 17, and son Noah, 14, ended their engagement in 2018 after a decade-long relationship.
