Leonardo DiCaprio, 50, and bikini-clad girlfriend Vittoria Ceretti, 26, hit the beach on St. Barts vacation

Leonardo DiCaprio and Vittoria Ceretti are closing out 2024 in paradise.

The couple was spotted relaxing on the beach in St. Barts on Saturday after spending the holidays together in Los Angeles.

While the Oscar winner, who turned 50 last month, kept things simple in a pair of black swim trunks and dark shades, the model, 26, showed off her svelte physique in a silver Blumarine thong bikini ($495).

The tiny two-piece featured a rhinestone logo on the bust and a bedazzled butterfly on the bottoms. Ceretti pulled her hair back in a claw clip and completed the look with Balenciaga sunglasses.

The pair was all smiles as they took a dip in the clear blue water, with DiCaprio wrapping one arm around his girlfriend‘s waist.

They engaged in subtle PDA as the movie star held Ceretti up while treading water.

After drying off, DiCaprio and the Italian beauty joined a few friends on the beach as they tanned in a pair of red chairs.

Before jetting off to the Caribbean, the lovebirds spent Christmas Eve together in California.

The “Wolf of Wall Street” star and Ceretti rang in the holiday alongside a group of pals at Chateau Marmont in West Hollywood.

They were spotted out to dinner with the cover girl’s family a few days later.

DiCaprio and Ceretti reportedly met at the Cannes Film Festival in May 2023 — one month before she finalized her divorce from DJ Matteo Milleri.

Although the “Revenant” star and the catwalker kept their romance under wraps at the beginning, they went public by August 2023.

While an insider recently refuted claims that the pair got engaged, Page Six has reported that they are the real deal.

“From the looks of it, their romance is much more than a passing fling,” one source previously told us, as another noted that “they’re enjoying getting to know one another on a deeper level.”

Prior to their relationship, DiCaprio was linked to Gigi Hadid and Camila Morrone, whom he dated for four years before their summer 2022 split.

Meanwhile, Ceretti wed Milleri, 36, in January 2020. While it is unclear exactly when they separated, she stopped sharing photos of the artist known as Anyma in late 2022, and they were officially over by the summer of 2023.
