Adria Arjona Makes a Monster Truck Entrance

Arjona certainly didn’t make an ordinary red-carpet entrance.

The actress arrived at Regal L.A. Live in downtown Los Angeles in a monster truck inspired by Onslaught, the upcoming A24 action thriller in which she plays an Army sniper who must protect her young daughter from genetically engineered super soldiers.

Momoa captured the moment on video and shared it with his followers the following day. In the clip, he appeared stunned as Arjona’s truck came around the corner before celebrating her big premiere moment.

Arjona also shared photos of herself with the vehicle on Instagram, writing, “Still cant get over this,” while tagging Onslaught and A24.

Jason Momoa Is Proud of His Girlfriend

Momoa made it clear that he was more than happy to be there for Arjona’s latest project.

Sharing footage and photos from the premiere, the Aquaman star wrote, “Mi amor I’m so proud of you [you’re] such a badass,” while encouraging fans to see the film in IMAX when it arrives in theaters.

The supportive message comes as Arjona takes on one of her most action-heavy roles to date.

Momoa has previously spoken publicly about how much he enjoys supporting Arjona’s career. Earlier this year, he told PEOPLE that she is “the love of my life” while discussing their schedules and their ability to support one another’s professional projects.

The Couple Shares a Sweet Red-Carpet Moment

Momoa and Arjona also shared a sweet moment together on the red carpet, posing for photographers and sharing a kiss.

Arjona wore a black strapless dress with an exposed corset detail, while Momoa opted for a gray checked suit with a black shirt underneath. Their appearance quickly became one of the memorable moments from the premiere.

The couple has generally kept their relationship relatively private, although they have occasionally offered fans glimpses of their romance through social media and public appearances.

How Jason Momoa and Adria Arjona’s Relationship Began

Momoa and Arjona first met while working together on the 2021 Netflix film Sweet Girl.

Their romantic relationship became public in 2024, when Momoa shared photos from a trip to Japan featuring Arjona and referred to her as his “mi amor.”

Since then, the pair have appeared together at various industry events and supported each other’s work.

Most recently, Momoa has continued to publicly celebrate Arjona’s career, including sharing photos from her Vogue Latinoamérica shoot shortly before the Onslaught premiere.

What Is Onslaught About?

Onslaught is directed by Adam Wingard and stars Arjona alongside Dan Stevens, Eric Wareheim, Reginald VelJohnson, Michael Biehn, Alex Pereira, Drew Starkey, and Rebecca Hall.

According to A24’s official synopsis, the movie follows an Army sniper who is forced into action when a rogue group of genetically engineered super soldiers escapes into the desert. Her mission becomes even more personal as she fights to protect her young daughter.

The role gives Arjona the opportunity to step into a physically demanding action performance, which makes Momoa’s “badass” description particularly fitting for the film’s central character.

When Does Onslaught Hit Theaters?

Onslaught is scheduled to arrive in theaters, including IMAX, on September 4, 2026. A24 lists Adam Wingard as the director and Arjona, Stevens, Wareheim, VelJohnson, Biehn, Pereira, Starkey, and Hall among the cast.

With the premiere now behind them, Arjona is preparing to introduce audiences to a very different side of her acting career.

And if Momoa’s reaction to her monster-truck arrival is any indication, he couldn’t be more excited to see her take on the role.
