Jacob Elordi and girlfriend Olivia Jade Giannulli are still enjoying the Italian coast!

On Sunday, Sept. 29, the Euphoria star, 27, and the influencer, 25, were photographed soaking up the sun while on vacation in Sardinia, Italy.

Giannulli sported a brown and blue bikini and a straw hat, while Elordi wore a pair of dark blue and green patterned swim trunks. Elordi wore bright green baseball cap, and at one point kept his long hair off his face with a pink claw clip. Both wore sunglasses, with Elordi choosing a pair of oversized aviators, and Giannulli wearing wayfarer-style sunglasses.

Elordi appeared to be honing his craft by reading a copy of Jean Cocteau’s The Art of Cinema.

Over the weekend, they were seen with Giannulli’s parents, Lori Loughlin and Mossimo Giannulli, on the Italian island on Saturday, Sept. 28.

That day, the four were photographed on a yacht, enjoying the Mediterranean Sea. Giannulli, who wore a purple bikini, took a dip in the sea alongside Elordi. The younger couple spent some time in the water together before heading back to a yacht, where Loughlin, 60, and Mossimo, 61, relaxed side by side.

Elordi and Giannulli later changed into more clothes and joined her parents on lounge chairs.

Before their beach vacation, Elordi and Olivia were seen together on Sept. 16, at her sister Bella Giannulli’s 26th birthday at Funke restaurant in Beverly Hills, Calif., according to E! News.

The couple have had an on-again, off-again relationship since at least late 2021.  They were first linked that year, when they were seen getting coffee together in Los Angeles, a month after Elordi split from model Kaia Gerber.

At the time, an insider told PEOPLE that Giannulli and Elordi were “casually dating,” while another source denied it. The two reportedly broke up in August 2022 because neither was interested in pursuing anything serious.

Nearly a year later, the couple were photographed on vacation together in Italy, on Lake Coeur d’Alene in Idaho with her parents and together in New York City’s Soho neighborhood, per the Daily Mail.

In July 2023, PEOPLE confirmed that the pair were officially back together, with a source saying, “They are 100 percent going strong.” The insider added, “[It’s] getting serious.”

Elordi recently finished filming Guillermo del Toro’s Frankenstein adaptation, in which he plays Frankenstein’s Monster, for Netflix. He also stars in On Swift Horses, which premiered at the Toronto International Film Festival in September.
