Alessandra Ambrosio showed off her model body while soaking up the sun on the beach in Miami on Friday – amid rumors she’s secretly engaged to her boyfriend.
The Brazilian runway maven, 45, looked tanned and toned in a pastel yellow bikini with white straps.
She wore a straw cowboy hat over her brunette hair as she seemingly took part in a beach photo-shoot.
The mother-of-two was wearing little to no makeup, which allowed her to show off her radiant, sun-kissed glow for the camera.
Ambrosio accessorized her look with a pair of aviator sunglasses and stacks of gold jewelry.
One particular piece of jewelry that stood out among her accessories was a massive, sparkling diamond situated on her left ring finger.

Her outing comes shortly after she fueled rumors she is engaged – or even married – to her longtime boyfriend Buck Palmer.
Ambrosio has been dating the handsome jewelry designer since late 2024.
The mom of two shares daughter Anja, 17, and son Noah, 14, with her ex-fiancé Jamie Mazur.
The couple first sparked engagement rumors when the former Victoria’s Secret Angel shared photos on Instagram earlier this spring and casually revealed a gold band situated on her ring finger.
‘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,’ a source exclusively told The Daily Mail in April.
‘It is likely that he designed that ring she is wearing on her wedding finger because that’s his job,’ the insider noted. ‘He designs jewelry.’
Ambrosio and Palmer were first romantically linked at a party during Miami’s Art Basel in 2024.
Insiders confirmed at the time that the smitten fashion model hoped to be with her new partner ‘for her entire life’ due to their deep connection.

She has been dating jewelry designer Buck Palmer for two years. Earlier this year, the couple were rumored to be secretly engaged, or even married after they were both seen with matching gold bands on their ring fingers
‘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 exclusively dished to the Daily Mail at the time.
‘She has been through the wringer in relationships but really truly believes in love and feels like she finally found it.’
In 2025, Ambrosio told Us Weekly that she and her beau connect through their ‘passion for life.’
‘We just love life to the fullest,’ she told the outlet.
She added: ‘We love living life and spending time together and enjoying every little thing.
‘I guess it’s the little things, sometimes, that count more. Whatever we do, we both just have this passion for life.’
