Leonardo DiCaprio, 50, is supported by his glamorous girlfriend Vittoria Ceretti, 27, as he leads star-studded red carpet arrivals at world premiere of One Battle After Another in Hollywood

Leonardo DiCaprio had the support of his girlfriend Vittoria Ceretti on Monday, as he led the star-studded attendees at the world premiere of his new film, One Battle After Another, at TCL Chinese Theatre in Los Angeles.

The acclaimed actor, 50, cut a dapper figure in a fitted black suit and button-up white shirt as he arrived on the red carpet.

And while she didn’t pose for photos alongside her famous boyfriend, Vittoria, 27, still stole the show in an elegant white draped gown.

The striking number boasted a thigh-high slit and was slashed open at the sides, flashing a glimpse of the Italian model’s long legs and a hint of side boob.

Dripping in diamonds from a glitzy bangle to her bejewelled serpent ear cuff, Vittoria looked in high spirits as she cheered on Leo from the sidelines, taking snaps of the adoring crowd of fans.

Also turning out to support the film was Leo’s fellow castmembers and Hollywood heavyweights, Sean Penn, Benicio del Toro, Regina Hall and Teyana Taylor.

Benicio, 58, put on a debonair display in a black suit and coordinating collared shirt, complete with a silk tie.

The Oscar winner – who plays Sensei Sergio in the film – was quick to greet his co-star Sean, 65, who looked sharp in a a navy blue blazer and tie.

While Teyana, 34, who stars as Leo’s love interest in the movie, showcased her fashion forward sense of style in a bold leather number.

The singer’s off-the-shoulder gown featured a structured silhouette and layers of draped fabric, as well as matching evening length gloves.

She elevated both the look and her height with a pair of towering platform heel boots, and added some sparkle with a slew of diamond rings and bracelets.

Regina, 54, was the picture of sophistication in a flowing beige gown, boasting a plunging neckline to showcase her décolletage and a corsetted bodice to cinch her in at her tiny waist.

The two stunning actresses posed alongside newcomer Chase Infiniti, who plays Willa, the daughter of Leo and Teyana’s characters.

The 26-year-old ensured all eyes were on her in a satin champagne gown encrusted in an intricate pattern of sparkling beads.

Vittoria and Leo first sparked romance rumors in August 2023 during an ice cream date in Santa Barbara, and The Wolf Of Wall Street actor was then seen at Milan Fashion Week to support her the following month.

Over the course of their time together, Vittoria has been seen on occasion with a ring on her wedding finger, but sources have insisted she and Leo are not engaged.

In March, the model admitted she found it ‘extremely annoying’ to be reduced to just ‘Leonardo DiCaprio’s girlfriend’.

Speaking to Vogue France , she sidestepped using Leo’s name, instead referring to him simply as a ‘very, very famous movie star’ while referencing his iconic role in Titanic, which she branded ‘iconic’.

However Vittoria kept her distance from public labels and shared that the pair’s bond is strong enough to dodge any jealousy.
