Leonardo DiCaprio tried to fly under the radar for his first Met Gala.

The actor made his debut at the star-studded event Monday night to support girlfriend Vittoria Ceretti — but refrained from walking the red carpet.

Instead, the “Titantic” star, 50, joined his 26-year-old partner inside.

The couple were caught on camera, with DiCaprio attempting to shield his face in the black-and-white Instagram shot Vogue shared Wednesday.

The Oscar winner looked sharp in a tuxedo.

Ceretti, for her part, honored the evening’s “Superfine: Tailoring Black Style” theme in a pinstriped Moncler x EE72 dress with matching gloves, a train and an oversized hood.

The model completed her look with black heels and Briony Raymond jewelry.

Ceretti and DiCaprio have been linked since they were spotted packing on the PDA at an Ibiza nightclub in 2023.

While the couple primarily keep their romance under wraps, Ceretti described an “extremely annoying” part of it last month.

“As soon as you’re in a relationship with someone who has a larger following than you, you become ‘girlfriend of’ — or ‘boyfriend of,’ for that matter,” she told Vogue France in March.

“Suddenly, people are talking about you as so-and-so’s girlfriend who was so-and-so’s ex,” Ceretti explained. “So it’s not nice to think that you can’t love whoever you want, because of the labels people need to stick on you.”

While she requested not to “go into details” about her connection with DiCaprio, Ceretti did reveal that they met in Milan, Italy.

“If you know you love each other, then there’s no reason to be alarmed,” she said of having a high-profile boyfriend. “Because love protects and gives confidence.”

DiCaprio has previously dated Gigi Hadid, Camila Morrone and more models.

We hear that the Golden Globe winner “doesn’t see himself ever getting married” to Ceretti despite being “happy with where things are between them.”
