Leonardo DiCaprio's girlfriend Vittoria Ceretti, 26, goes TOPLESS with shirtless Titanic star, 49, on yacht off Cannes

Leonardo DiCaprio's supermodel girlfriend Vittoria Ceretti took off her bikini top as they frolicked on a luxurious yacht off the South Of France this week.

The 49-year-old Titanic star and his 26-year-old flame have spent a chunk of the summer cruising around the Mediterranean, stopping at such fashionable pleasure spots as Sardinia.

While they were in Italy, Vittoria was spotted sporting a ring on her engagement ring, unleashing an avalanche of rumors about the true state of their relationship.

Her left hand was bare of jewelry when she was seen gamboling around on the yacht near Cannes this Friday, accompanied by her shirtless celebrity boyfriend and another bikini bombshell.

Vittoria indulged in a bit of sunbathing on a deck chair - and removing her barely-there swimsuit top, with its straps seen dangling down her sides.

The bikini was so tantalizingly skimpy that the cups were completely obscured by her hands as she slid the top off, whilst working on her August tan.

Meanwhile Leo could be glimpsed enjoying a dip in the ocean, then clambering back up onto the vessel, where a crew member was already waiting for him with a towel.

He was dripping wet as he sauntered across the deck, showing off his burly torso by by wearing nothing but sunglasses and a set of blue swim trunks.

The bikini bombshells were evidently unable to retain his undivided attention, as he sat staring at his phone while they flaunted their figures sunbathing in front of him.

Leo had a few round marks on his lower back that resembled the imprints left by cupping therapy, a treatment from traditional Chinese medicine in which hot cups are applied to the skin. 

During his latest summer jaunt in Europe, Leo has occasionally been accompanied by his longtime pal Tobey Maguire, who was spotted a few weeks ago taking Vittoria on a jet-ski ride as they all went yachting together.

The two actors share a tight bond stretching back to the 1990s, when they led a group of men about town famously dubbed the 'P***y Posse' by New York magazine. 

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 confirmed at the time that the couple were not in fact 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 away 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.

Years earlier, she was briefly linked to the model then known as Natalie Westling, who has since undergone a gender transition and is now called Nathan Westling.

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

The smoldering sensation 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,' the Lombard fashion maven explained to Elite Model Look. 

'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.'
