Leonardo DiCaprio, 50, and Vittoria Cetti, 26, enjoy the evening at Chateau Marmont before Christmas

Leonardo DiCaprio and his girlfriend Vittoria Cetti were spotted enjoying a night out in Los Angeles just before Christmas.

The 50-year-old movie star took the 26-year-old Italian model to the Chateau Marmont, a legendary Sunset Boulevard hotel.

Rumors have swirled that Leo, one of the most famous bachelors in the world, has become engaged to Vittoria after dating for over a year.

Amid the blizzard of speculation, Leo and Vittoria were seen indulging in a night out with friends at the ritzy West Hollywood establishment.

They matched each other in black, she in a long coat draped over her enviably willowy frame and he in a shorter casual jacket.

Vittoria, who recently posted bikini snapshots from her trip to the Solomon Islands, was decked out in a chic black blouse and baggy gray jeans.

Sharpening her unmistakable features with make-up, the sizzling sensation let her dark hair fall in silky drapes to frame her glowing complexion.

Last month she and Leo enjoyed a holiday to Mexico for his 50th birthday, accompanied by her mother Irmelin Indenbirken, 81.

Engagement rumors have circled Leo and Vittoria a few times this year, which intensified last month due to an email to the gossip blog DeuxMoi.

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

They have been together since she turned 26, despite heavy rumors that Leo has a ’25 and under’ rule for his girlfriends.

However, in March of this year, Leo was seen putting on a cozy performance at a pre-Oscar party with none other than singer Teyana Taylor, with whom he has filmed the upcoming Paul Thomas Anderson film.

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

Later that month, he was seen enjoying a lunch date with Vittoria in Los Angeles, indicating that their relationship was still going strong.

Leo and Teyana were spotted together again last month when he reportedly attended the New York party she threw to celebrate the Rock And Roll Hall Of Fame induction.

Hours after his date with Vittoria, Leo is said to have gone with a group of friends to Manhattan nightclub The Stafford Room – the site of Teyana’s party.

Vittoria did not attend the party, where Leo and Teyana ‘danced very closely’ and shared ‘a lot of laughs’, according to one Page six source.

“They hung out all night and they were basically cornered together,” the insider added, noting that Teyana seemed “very protective” of Leo.

The source described Leo as ‘flirty’ but claimed he did not indulge in any public displays of affection for Teyana at the club.

Teyana and Leo reportedly left the venue together at 03.00, but it is still unclear whether they then got into the same car.

But an insider then exclusively informed DailyMail.com that the equation between Leonardo and Teyana is strictly platonic.

The pair apparently became friends while filming their upcoming film The Battle Of Baktan Cross, and he has helped her cope with her split from former pro basketball player Iman Shumpert.

‘They are not dating but are very close and have been giving each other a lot of advice recently. Leo has also been supporting Teyana as she deals with the fallout from her messy breakup with Iman,’ the source said.

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

They were first linked in August 2023, following a flurry of rumors linking Leo to Vittoria’s fellow supermodel Gigi Hadid.

Vittoria was previously married from 2020 to 2023 to 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 reassignment and is now Nathan Westling.

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