They Said It Wouldn’t Last—But Jason Momoa and Adria Arjona Just Shut Down Every Doubter at Cannes

CANNES, FRANCE — On a night swirling with cinematic magic and star power, it wasn’t just the world premiere of Splitsville that captured hearts at the 2025 Cannes Film Festival—it was the glowing romance between Adria Arjona and Jason Momoa that stole the show.

Arjona, 33, shared a series of intimate photos and joyful videos to Instagram after Monday’s premiere, delighting fans with behind-the-scenes glimpses of her and Momoa, 45, arm in arm on the legendary red carpet. Her message was brimming with gratitude and affection: “SPLITSVILLE premiere at @festivaldecannes! The most special night with the most special people. … I love that I got to share such a special moment with my love and my forever favorite date @prideofgypsies ❤️.”

Momoa, never shy about showing his support, quickly replied in the comments, “❤️❤️so proud of you and so happy to be by your side. ❤️❤️❤️❤️” Their public declarations are the latest in a series of heartfelt exchanges since the pair made their relationship official in May 2024. The couple’s chemistry first sparked media speculation at the SNL 50th anniversary celebration, where they walked their first red carpet together, and they’ve been each other’s biggest fans ever since.

Arjona’s Cannes celebration marks another milestone for the actress, whose star continues to rise with acclaimed roles in projects like Disney+’s Andor, Blink Twice, and Hit Man. At Cannes, she walked hand-in-hand with costar Dakota Johnson, 35, who plays a pivotal role in Splitsville. Arjona’s Instagram post also featured tributes to the film’s creative team, including director Mac Covino, thanking them for trusting her with the lead role of Ashley—a woman whose request for a divorce sets off a chain reaction in the film’s romantic entanglements.

The couple’s public affection reflects a relationship built on mutual pride and unwavering support. Earlier this year, Arjona supported Momoa at the U.K. premiere of his highly anticipated Minecraft Movie, appearing alongside Momoa’s mother, Coni, and later sharing memories from the whirlwind weekend. “What more can a girl ask for,” Arjona wrote, reflecting on celebrating love, work, and friendship all at once.

Now, with Splitsville set to hit theaters on August 22, Arjona’s radiant Cannes appearance—and Momoa’s steadfast presence at her side—showcase not only a love story but a partnership that thrives amid the flashbulbs and frenzy of international stardom. As Arjona herself put it: “I’ll never forget it.”

With every red carpet appearance, it’s clear: Adria Arjona and Jason Momoa are writing a Hollywood love story that’s only just beginning.
