Alessandra Ambrosio’s boyfriend, Buck Palmer, confirms they have not tied the knot despite both sporting wedding bands in a recent social media post from their Indonesia vacation. The pair celebrated her 45th birthday with island adventures, where she captioned a bikini photo: “Island days, wild hearts ✨ what a beautiful birthday spending the week at this magical place.”

Addressing the Rumors

The Australian jewelry designer addressed speculation directly, stating, “Not yet.” Sources close to the couple note their relationship has grown serious over the past year, with many believing they are headed toward engagement. “Everyone feels like she and Buck are headed that way because they are very serious and in love,” one insider shared. “It is likely that he designed that ring she is wearing on her wedding finger because that’s his job—he designs jewelry.”

The duo first sparked romance rumors at a 2024 Art Basel party in Miami. Insiders reveal Ambrosio views Palmer as a lifelong partner. “Alessandra knows who her New Year’s Eve kiss is going to be, and she hopes to have the same man to kiss for every New Year’s Eve for her entire life,” a source indicated. “She has been through the wringer in relationships but really truly believes in love and feels like she finally found it.”

Relationship Background

Ambrosio and Palmer have dated since late 2024 and frequently share moments online. They appeared together at the Vanity Fair Oscar party in Los Angeles on March 15. Palmer brings adventure and compatibility, making Ambrosio “happier than ever,” according to friends. “He has a great sense of adventure and likes to try new things; he is perfect for her,” an insider said. “She is not opposed to getting married; she is being open with her heart, so who knows—they may walk down the aisle.”

Past partners have sometimes resented her fame and success, but Palmer stands out. “Buck doesn’t do this,” a source explained. “He is incredibly successful in his own right as a jewelry designer and of course designs special pieces just for her.”

Past Romances

The supermodel, never previously married, was engaged to businessman Jamie Mazur from 2008 to 2018. They share daughter Anja, 17, and son Noah, 13. She later dated Nicolo Oddi from 2018 to 2020 and model Richard Lee from 2021 to 2023.

Palmer was married to Australian model Ashley Hart for two years, ending in 2017.

In March 2019, Ambrosio launched her beachwear brand, GAL Floripa, co-founded with sister Aline Ambrosio and friend Gisele Cória, inspired by their Brazilian hometown of Florianópolis.
