Alessandra Ambrosio and Buck Palmer Are Engaged After Romantic Beach Proposal: ‘Here’s to Forever’

Alessandra Ambrosio is preparing to walk down the aisle after revealing that boyfriend Buck Palmer proposed during a romantic beachside moment the couple had quietly kept private for months.

The Brazilian supermodel, 45, announced on Tuesday, Aug. 11, that she and the Australian jewelry designer are officially engaged, sharing a series of intimate photographs and a video from Palmer’s proposal, which actually took place four months earlier in April.

Ambrosio revealed the happy news on Instagram, giving fans their first look at the carefully planned moment.

In the photos, Palmer can be seen getting down on one knee inside a large heart drawn into the sand as Ambrosio stands in front of him on the beach.

Other images capture the couple celebrating afterward, embracing beside the ocean and running together through the water.

A drone video provided an even wider view of the romantic scene, showing Ambrosio and Palmer smiling together from the center of the heart etched into the shoreline.

“I’d choose you in this life and every life. Here’s to forever, my love. 💍✨,” Ambrosio wrote alongside the announcement.

A Proposal They Kept Secret for Four Months

Although fans only learned about the engagement on Aug. 11, Ambrosio explained that the proposal happened months earlier.

In a message shared to her Instagram Stories, the longtime Victoria’s Secret star revealed that she and Palmer had deliberately chosen to enjoy the milestone privately before announcing it publicly.

“Four months ago, we said YES to forever. 💍 🤍,” she wrote.

“We’ve been holding this beautiful moment close to our hearts. and now we’re so happy to finally share it!”

Another image showed the newly engaged couple kissing on the beach while Palmer lifted Ambrosio into the air.

“Nothing feels better then been in your arms💫,” she captioned the affectionate photograph.

The announcement marks another major step in a relationship that became public less than two years ago but quickly developed into a highly visible romance filled with travel, beach getaways and affectionate social media tributes.

Their Romance Became Public in December 2024

Ambrosio and Palmer officially confirmed their relationship in December 2024.

The model initially shared a heartfelt birthday tribute celebrating Palmer, offering one of the clearest signs at the time that their relationship had become serious.

Later that month, she posted several romantic photographs of herself and Palmer together at Praia Brava in Brazil.

The images showed the couple kissing on the beach, publicly confirming what fans had already begun to suspect.

Their relationship continued to appear regularly on social media as the couple entered 2025 together.

On Jan. 2, Ambrosio shared another photograph of herself embracing Palmer as they welcomed the new year with an intimate sunrise.

“☀️First sunrise of 2025 to bring in the new year, left the party to enjoy a special moment witnessing nature put on a show for just the two of us… magic! 💫,” she wrote.

The post reflected a theme that has continued throughout their relationship: traveling together while turning ordinary or scenic moments into shared memories.

Palmer Opened Up About Falling in Love

Just two days after Ambrosio’s New Year’s post, Palmer shared his own emotional tribute while looking back on 2024.

Among the highlights of his year was finding love with Ambrosio.

“To top off this year finding and falling in Love with such an amazing partner,” Palmer wrote, describing her as someone who inspired him every day.

He also praised the connection they had developed through both exciting adventures and everyday life.

Palmer described Ambrosio as “someone in which we have so much fun in the ordinary” and someone who “ignites a passion for life and makes everything more bright.”

He concluded his message by expressing gratitude for their relationship.

“im So so glad I found you again my 🤍. I couldn’t be more thankful,” he wrote.

The post included a smiling selfie of the couple together.

His reference to having “found” Ambrosio again suggested a deeper personal connection behind a romance that had only recently become public, though the couple have generally allowed their shared photos and travels to tell much of their story.

A Relationship Documented Through Travel

By the following month, Ambrosio and Palmer had taken another unusual step together: creating a joint Instagram account called ourdream1111.

Rather than focusing exclusively on formal relationship milestones, the account has documented the couple’s adventures and travels around the world.

From beaches to international destinations, their posts have offered followers regular glimpses into their life as a couple.

Travel has also been a recurring part of Ambrosio’s public life for years.

The model, who was born in Brazil and became internationally famous through Victoria’s Secret, frequently shares photographs from tropical destinations, fashion events and vacations with family and friends.

Her relationship with Palmer appeared to fit naturally into that lifestyle, with many of their most romantic public moments taking place outdoors and near the ocean.

Perhaps fittingly, Palmer ultimately chose a beach as the setting where he asked Ambrosio to marry him.

Ambrosio Was Previously Engaged to Jamie Mazur

This will not be Ambrosio’s first engagement.

The model was previously engaged to businessman Jamie Mazur, with whom she shared a long-term relationship.

Ambrosio and Mazur became engaged in 2008 and remained together for approximately a decade before ending their engagement in 2018.

They share two children.

Their daughter, Anja, is 17, while their son, Noah, is 14.

Ambrosio has frequently shared moments with her children publicly over the years, including birthdays, vacations and family celebrations, while continuing her international modeling and business career.

Palmer Was Previously Married

Palmer also has a previous marriage.

The Australian jewelry designer was formerly married to model Ashley Hart, the sister of Victoria’s Secret model Jessica Hart.

According to Women’s Health, Palmer and Ashley were married from 2015 until 2017.

Years later, Palmer and Ambrosio began a relationship that would become publicly known in late 2024.

Less than a year after confirming their romance, Palmer proposed.

From Victoria’s Secret Fame to a New Personal Chapter

Ambrosio has spent decades as one of the most recognizable figures in international fashion.

She became especially associated with Victoria’s Secret, where her years as an Angel helped make her one of the most prominent Brazilian models of her generation.

But her latest announcement has little to do with runways, campaigns or fashion shows.

Instead, Ambrosio’s photographs focused on a private personal milestone: Palmer kneeling before her on a beach, surrounded only by sand, water and the giant heart marking the place where their engagement began.

For four months, the couple kept that memory largely to themselves.

Now, nearly two years after publicly confirming their relationship, Ambrosio and Palmer are sharing the beginning of their next chapter.

And Ambrosio summarized that future with just a few words:

“Here’s to forever, my love.”
