Leonardo DiCaprio got stung by a jellyfish while enjoying another idyllic yacht day in Sardinia with girlfriend Vittoria Ceretti this week.

The Oscar-winner, 49, showed off his shirtless frame as he pulled up his swimming trunks to reveal a angry red mark on his leg – while a concerned Vittoria, 26, checked out the injury.

Titanic star Leo splashed his leg in the outdoor shower as he chatted with his partner – who recently ignited engagement speculation by wearing a silver diamond ring.

Vittoria displayed her supermodel frame in a tiny black string thong bikini which showcased her pert posterior and taut midriff.

The Revenant actor was also seen relaxing aboard the yacht with his hair in a top knot before sporting some goggles as he went swimming.

He is holidaying with BFF Tobey Maguire, 49, who is also in an age-gap romance with Babette Strijbos, 24.

With the new couple seen kissing in exclusive DailyMail.com photos last week.

Leo and Vittoria — who have been dating since summer 2023 — first sparked engagement speculation earlier this year when Vittoria was seen wearing a silver diamond ring in LA.

But an insider told TMZ at the time that the couple were not engaged and that she’d owned that particular ring since 2022.

The heart-shaped ring appears to be a new addition to Vittoria’s jewelry collection and it has renewed interest in the idea of Leonardo — Hollywood’s most infamous Lothario — finally settling down.

Vittoria also wore a similar ring on her right pinky finger during Wednesday’s lunch date in Nerano.

Leo and Vittoria were first linked over the summer of last year, when she had just turned 25, and have been spotted together on several occasions since.

However in March of this year, Leo was spotted putting on a cozy display at a pre-Oscars party with none other than songstress Teyana Taylor, with whom he has been filming the upcoming Paul Thomas Anderson movie.

At the pre-Oscars party, Teyana was glimpsed gently caressing Leo’s face, and he in turn was seen tapping her on the derriere, according to TMZ.

However, later that same month, he was spotted enjoying a lunch date with Vittoria in Los Angeles, indicating their relationship was still going strong.

Vittoria was even sporting a gleaming silver ring on her left hand fourth finger – but TMZ reported at the time that the couple were not engaged.

Near the end of March, Leo and Vittoria were spotted out to dinner at the Santa Monica  celebrity hot spot Giorgio Baldi – and she then drove them from the venue.

‘The restaurant has been Leo’s favorite for years and he’s enjoyed date nights with Vittoria several times,’ an insider explained to People.

‘She’s, of course, Italian, so she takes care of ordering all the favorites,’ said the source. ‘She is very cute, sweet and charming. Leo seems to really like her.’

Vittoria and Leo are said to have met at last year’s Cannes Film Festival, where his new Martin Scorsese movie Killers Of The Flower Moon was premiering.

They were first linked in August 2023, after a flurry of rumors that had connected Leo to Vittoria’s fellow supermodel Gigi Hadid.

Vittoria was previously married from 2020 until 2023 to the Italian DJ Matteo Milleri, who is part of the Berlin-based duo Tale Of Us.

Vittoria was discovered in 2012 and has since walked over 400 fashion shows, as well as covering various international editions of Vogue 23 times.

She has spoken candidly in the past about the habits that have enabled her to retain her lithe physique and luminous complexion.

‘I always try to eat healthily. I go to the gym when I’m home or do some yoga if I have the time off,’ she explained to Elite Model Look.

‘I always make sure to wash my face at morning and at night, moisturizing my skin before I leave home or before I go to bed,’ she added.

‘I apply a face mask for when my skin feels tired or if I’ve worked for a while,’ noted Vittoria, who originally hails from Brescia in the shadow of the Italian Alps.

‘I try not to eat lots of junk food,’ she told W.’In the morning I always eat fruit and yogurt with cereal. And for lunch and dinner I always have vegetables as a side.’

As far as beverages are concerned, she shared: ‘I love smoothies and Vitamin Water, but I always have some iced tea in my fridge!’

In the workout department, she dished: ‘When I’m not working I go for runs. I live around many parks, so it’s nice to feel like you’re not surrounded by the city.’

Leo has a history of high-profile relationships, primarily with gorgeous models under the age of 25.

Notably, he had a famous five-year romance with model Gisele Bündchen, starting when she was just 18.

This was followed by another five-year relationship with Bar Refaeli and a brief fling with actress Blake Lively.
