Millie Bobby Brown Turns Heads in String Bikini Amid Whirlwind Romance With Jake Bongiovi

Millie Bobby Brown is stepping into summer with confidence, style, and no shortage of attention. The 21-year-old “Stranger Things” breakout star took to Instagram on Friday to post a trio of stunning photos from a beach getaway — and fans, along with a few famous friends, were quick to react.

In the photos, Brown poses effortlessly by the shoreline, hands behind her head and sun kissing her golden tan. Her blue and green paisley string bikini featured delicate lace trim and a gold pendant dangling from the beaded center, highlighting her fit frame and relaxed beachside mood. The triangle-style top and matching bottoms made for a bold yet tasteful fashion statement that drew instant admiration.

Brown accessorized the look with a subtle nod to designer flair — a pair of oversized sunglasses from Mondottica, a light purple beaded necklace, and classic gold hoop earrings. The actress kept her caption simple: just three emojis — a sun, an ocean wave, and a seashell — letting the images speak for themselves.

Among the flood of fan comments, celebrity Paris Hilton chimed in with a heart-eyes emoji, a sign that Brown’s post didn’t just wow her fanbase, but her fellow stars as well.

While the beach photos made headlines, they also spotlight a new chapter in Brown’s life — one that’s closely tied to her relationship with Jake Bongiovi, son of rock icon Jon Bon Jovi. The young couple has become one of the most-watched pairs in entertainment this past year, after their high-profile romance culminated in not just one, but two weddings.

In May 2024, Brown and Bongiovi tied the knot in an intimate family ceremony when she was just 20 and he 22. The news sparked both admiration and curiosity about the couple’s decision to marry so young. Then, in October, they exchanged vows again in a romantic ceremony held in Tuscany, Italy.

Fans got a rare glimpse into their honeymoon when Brown posted a never-before-seen snapshot from their trip to Croatia. In it, she wears a custom white Oceanus swimsuit embroidered with Jake’s initials, “JB,” and a black heart over her right hip. The look was paired with a gray bow motif across the chest, offering a blend of sweetness and sensuality. Bongiovi matched the sentiment in his own way, wearing a white short-sleeve button-down with the word “Hubby” embroidered in gold above the pocket.

The couple, who announced their engagement in April 2023, have maintained a strong public front, often sharing glimpses of their life together on social media. In May, Brown paid tribute to her husband on his 23rd birthday with a carousel of candid images, continuing the narrative of a youthful love story rooted in both fun and commitment.

Speaking to Vanity Fair in February 2025, Brown addressed the timing of their marriage. “People ask us all the time why we got married so young,” she said. “But when you know, you know. Jake and I wanted to build a life together now, not later.”

Her father-in-law seems to support the decision. Shortly after their wedding, Jon Bon Jovi told BBC’s The One Show, “They are great. They are absolutely fantastic. It was a very small family wedding, and the bride looked gorgeous. And Jake is happy as can be. It’s true.”

Now, with her hit Netflix franchise nearing its final chapter and other projects — including the Enola Holmes series — expanding her acting repertoire, Brown appears to be enjoying a well-earned moment of rest and romance. Her recent beachside snapshots reflect not only her physical confidence but also a personal glow that seems to come from feeling fully at ease in her new role as both actress and wife.

For Brown, 2025 is shaping up to be the year of balance — a blend of blockbuster ambition and beachside bliss. Whether she’s lighting up red carpets, relaxing by the sea, or sharing quiet moments with Bongiovi, it’s clear the young star is living life entirely on her terms.

And fans? They’re watching — and cheering — every step of the way.
