Alessandra Ambrosio was proudly showing off her new boyfriend Buck Palmer on Instagram on Tuesday.

The 43-year-old Victoria’s Secret model was seen kissing the Australian jewelry designer as they posed at a home in Brazil.

They were both dressed up as they rang in 2025.

‘So grateful for all my Loved ones this year!! Ending on such a high note gathering all my closest friends and family at home… ☀️❣️Looking forward to a beautiful year ahead and sending you all Good vibes for this new year! ✨✨✨✨@mhternes,’ read her caption.

The images were by pH๏τographer Matias Ternes.

Alessandra had on a yellow and black summer dress with her hair partially down. And her new beau, whom she has been dating for the past several months, wore a cotton shirt with plenty of silver jewelry.

Also at the party were her two children whom she had with ex Jamie Mazur.

Last month they kissed on the beach.

Buck went shirtless, showing off his chiseled physique while wearing swim trunks, and he accessorized with chunky black sunglᴀsses and added a green cap for a splash of color.

The hat, which runs for about $50 from Good Quality Human, read ‘Mi Casa, Su Casa’ on the front, which was broken up by a large ‘LA’ design.

The colors perfectly matched the Brazilian flag, which fluttered in the breeze above Alessandra and Buck’s heads.

She let the loved-up pH๏τo do the talking and simply captioned her post with green, yellow and blue heart emojis.

According to her tagged location, the couple were enjoying the day at the popular beach Praia Brava, which is located on the north end of the large Santa Catarina Island, which is home to the state’s capital city, Florianópolis.

She later paid tribute to the city by naming her beachwear brand GAL Floripa, using a nickname for the capital.
