Millie Bobby Brown is having some fun in the sun.

The “Stranger Things” star sizzled in her latest Instagram post as she showed off her tanned and toned body in a string bikini Friday.

In a small carousel of photos, Brown struck a pose in a blue and green paisley-patterned bikini featuring white ruffled trim.

The actress kept her caption simple with just three ocean-themed emojis.

Her outfit was punctuated with some light jewelry and a pair of Mondottica Group sunglasses. She beat the heat by slicking her hair back into a bun.

The post was hot enough that it attracted the attention of “That’s Hot” hitmaker Paris Hilton, who commented with a heart-eyes emoji under the photos.

The “Enola Holmes” star, 21, appears to enjoy spending her time at the beach.

In May, she flashed husband Jake Bongiovi’s initials on one of her swimsuits in a never-before-seen Instagram photo as she wished him a happy 23rd birthday.

Brown wore the swimsuit, created by Oceanus — a brand who sells a similar beaded all-white style for $346 — on the couple’s Croatian honeymoon in October 2024.

The white beaded look was adorned with “JB” and a heart on the top right of the suit, as well as a huge bow across her chest.

“happy birthday hubby ❤️❤️❤️ there’s no one like you,” Brown captioned the birthday post.

The couple first wed in a secret ceremony in May 2024.

Months later, they tied the knot in a lavish second ceremony in October 2024.

Bongiovi and Brown celebrated their nuptials with two separate vacations. Before going to Croatia, the couple visited Porto Cervo, Sardinia, in June 2024, a month after their first wedding.
