Supermodel Alessandra Ambrosio has ignited a flurry of engagement speculation after she was spotted wearing a striking gold wedding band on her ring finger in a series of sizzling bikini photographs posted to Instagram on Thursday. The images, captured during a picturesque sunrise in Bali, were taken by her boyfriend, renowned jewellery designer Buck Palmer, hinting that their romance may be taking a more serious turn.
Instagram Official and Growing Romance
The couple, who have been dating since late 2004, made their relationship Instagram official in December 2024 when Ambrosio shared a heartfelt birthday tribute to Palmer, declaring her love publicly. In her latest post, captioned "Bali…at first light ✨☀️," she credited Palmer as the photographer behind the alluring snapshots, showcasing her in a pale blue bikini that revealed a tattoo on her lower back.
Sources Suggest Matrimony on the Horizon
While Ambrosio has not confirmed any engagement to friends, insiders close to the pair believe marriage could be imminent. A source exclusively told The Daily Mail, "If Alessandra is engaged she has not told her friends yet, but everyone feels like she and Buck are headed that way because they are very serious and in love, so this may be a big hint from her that they are headed toward matrimony."
The source added, "It is likely that he designed that ring she is wearing on her wedding finger because that's his job - he designs jewellery." The Daily Mail has reached out to Ambrosio's representatives for comment, but no official statement has been issued regarding the nature of the ring, leaving it unclear whether it signifies a promise, engagement, or wedding band.
Blossoming Relationship and Personal Happiness
According to insiders, the relationship between Ambrosio and Palmer continues to flourish. "She has never been happier because he has a great sense of adventure and likes to try new things, he is perfect for her," an insider revealed. Another pal commented, "She is not opposed to getting married, she is being open with her heart, so who knows they may walk down the aisle."
The couple first sparked romantic rumours after being linked at a party during Art Basel in Miami in 2024. At the time, sources confirmed that Ambrosio hoped to be with Palmer "for her entire life" due to their profound connection. "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 dished exclusively to The Daily Mail.
Past Relationships and Career Ventures
Ambrosio has faced challenges in previous relationships, with insiders noting she has been with men resentful of her fame and wealth. "She has been a serial monogamist in a sense and loves being in relationships but has been with men that are resentful of her fame and her money," the insider explained. However, Palmer, who is "incredibly successful in his own right as a jewellery designer," does not share these sentiments, often creating special pieces just for her.
Prior to dating Palmer, Ambrosio was engaged to American businessman Jamie Mazur from 2008 to 2018, with whom she shares two children: daughter Anja, 17, and son Noah, 13. Between Mazur and Palmer, she dated Nicolo Oddi from 2018 to 2020 and model Richard Lee from 2021 to 2023. Palmer was previously married to Australian model Ashley Hart for two years before their divorce in 2017.
Beyond her modelling career, Ambrosio launched her beachwear brand, GAL Floripa, in March 2019. She co-founded the lifestyle brand with her sister, Aline Ambrosio, and best friend, Gisele Cória, drawing inspiration from their hometown of Florianópolis, Brazil.
