Supermodel Alessandra Ambrosio is engaged to jewelry designer Buck Palmer. The couple announced their engagement on their joint Instagram page on Tuesday, marking nearly two years since they began their romance.
Ambrosio, 45, shared the news with the caption, "I’d choose you in this life and every life. Here’s to forever, my love." Palmer, 44, proposed on a beach in Indonesia. Ambrosio was seen wearing a string bikini during the proposal, and she later flashed her new diamond ring.
The couple first sparked engagement rumors in the spring when Ambrosio shared photos on Instagram featuring a gold band on her ring finger. A source told The Daily Mail in April that the ring was likely designed by Palmer, as jewelry design is his profession.
In mid-April, Ambrosio and Palmer, an Australian jewelry designer and former model, posted photos from an Indonesian vacation, with both wearing gold bands on their ring fingers.
The pair were first romantically linked at a party during Miami's Art Basel in 2024. Insiders confirmed at the time that Ambrosio felt a deep connection with Palmer and hoped to be with him for her "entire life."
Ambrosio told Us Weekly in 2025 that she and Palmer share a "passion for life" and enjoy "living life to the fullest" and "spending time together."
Ambrosio has two children, daughter Anja, 17, and son Noah, 14, from her previous engagement to Jamie Mazur. Their engagement ended in 2018 after ten years together.
In a 2023 interview with Schön. Magazine China, Ambrosio discussed the importance of a positive outlook and living in the present moment. She also expressed interest in hosting her own show and collaborating with emerging designers.
