Leonardo DiCaprio, girlfriend Vittoria Ceretti vacation in Ibiza with Tobey Maguire

Tobey Maguire is continuing to third-wheel Leonardo DiCaprio’s lavish summer vacation with girlfriend Vittoria Ceretti in Ibiza, Spain.

The trio were spotted relaxing on the sandy shores of the Mediterranean Sea alongside a group of friends on Wednesday, according to photos obtained by Page Six.

The “Titanic” actor, 49, was dressed casually in a white T-shirt, gray swim trunks and a tan Los Angeles Dodgers baseball cap.

The Italian model, 26, looked chic in a black sheer maxi dress layered over her cheeky snakeskin-print bikini. She accessorized with black sunglasses, a black-and-cream fedora and a woven Loewe beach bag.

Ceretti wore her long brown tresses in a singular braid that cascaded down her sunkissed back.

Meanwhile, Maguire, also 49, mirrored DiCaprio’s laidback style in a black tee, baggy board shorts, Ray-Ban sunnies and a black cap printed with the letter “M” on the front.

Ceretti and Maguire appeared to be getting along swimmingly as they chatted along the rocky Spanish coast.

DiCaprio, on the other hand, concentrated on his phone screen as the group seemingly waited around for the next activity.

As seen in other photos from the trip, the trio and their entourage were also spotted riding off in a luxurious motorboat packed with several bikini-clad models and other male friends.

Maguire was photographed basking in the sunshine while chatting with a friend on board the vessel.

Ibiza is a special place for DiCaprio and the Vogue cover star as they took their love public at a nightclub on the island with a steamy dance floor makeout last August.

From there, they were continuously spotted hanging out together around the globe, including in Paris for a dinner date, as well as in Milan, Italy, with DiCaprio’s mom.

A source exclusively confirmed to Page Six last September that the “Killers of the Flower Moon” star and Ceretti’s relationship was very serious.

“They’ve been spending quite a bit of time together over the past few months, and they’re enjoying getting to know one another on a deeper level,” the insider shared at the time.

It seems that Ceretti has even gotten Maguire’s stamp of approval considering how much they have been hanging out.

Last month, Maguire and Ceretti were seen riding on a jet ski together during a yacht excursion with DiCaprio in Portofino, Italy.
