Brazilian model has never looked better after turning 45 years old last month.

And the veteran proved she is still on top of her game as she posted new bikini images to Instagram this week.

She was on the beach on the Mayan Riviera in to promote her swimwear line GAL Floripa which she founded with her sister, Aline Ambrosio, and her best friend, Gisele Cória.

Interestingly, the images were taken by her Australian boyfriend Buck Palmer, who left the comment 'Gorgous Babi' on her Instagram post.

She tagged their joint Instagram account called OurDream1111 which chronicles their many exotic vacations together. Her friend hit the like button.

In April, Palmer revealed if he has married the supermodel after both were seen with wedding bands on in a social media post.

The Australian jewelry designer told The Daily Mail, 'Not yet.'

The couple have been dating since late 2024 and are often seen together on the beach.

Ambrosio has never been married before with her past boyfriends including Jamie Mazur, Nicolo Oddi and Richard Lee. Buck was before they called it quits in 2017.

A source told the Daily Mail in early April that the two have gotten very serious in the past year. 

'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 ,' a source told the Daily Mail. 

'It is likely that he designed that ring she is wearing on her wedding finger because that's his job - he designs jewelry.'

The Daily Mail has learned that things just keep getting better between Ambrosio and Palmer.

'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 said.

'She is not opposed to getting married, she is being open with her heart, so who knows they may walk down the aisle,' added the pal. 

The model and the designer were first romantically linked at a party in Art Basel in Miami in 2024.

Insiders confirmed at the time that the smitten fashion model hopes to be with her new partner 'for her entire life' due to the deep connection they share.

'Alessandra knows who her New Year's Eve kiss is going to be, and she hopes to ,' 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.'
