Adria Arjona and Jason Momoa made an appearance at the Cannes Film Festival for the premiere of 'Splitsville,' a new movie starring Arjona and Dakota Johnson. Arjona shared photos and videos on Instagram of herself and Momoa at the premiere, which took place on May 19, 2025, in Cannes, France.

In her Instagram post, Arjona expressed her gratitude and excitement for the film. She thanked director Michael Covino and costars Dakota Johnson and Kyle Marvin, stating she was proud of the film and everyone involved. She also expressed her affection for Momoa, calling him her 'love' and 'forever favorite date,' whom she has been publicly dating since May 2024.

Momoa responded to Arjona's post with a supportive comment, expressing his pride and happiness to be by her side. The couple's relationship became public in May 2024 after Momoa hinted at being in a relationship during a Comic Con event in the U.K.

The couple has been actively engaging with each other on Instagram and made their red carpet debut at the Saturday Night Live 50th anniversary special in New York City. Arjona shared her experiences of that weekend on Instagram, including launching her perfume with Moroccanoil and celebrating SNL's anniversary while holding Momoa's hand.

Arjona, known for her roles in 'Andor,' 'Blink Twice,' and 'Hit Man,' also attended the premiere of Momoa's 'A Minecraft Movie' in the U.K. in March, along with his mother Coni.

'Splitsville' features Arjona as Ashley, who seeks a divorce from her husband Carey (Kyle Marvin). According to a Cannes synopsis, the film follows Carey as he turns to his friends Julie (Dakota Johnson) and Paul (Michael Covino) for support, only to discover that their happiness is based on an open marriage. The situation becomes chaotic when Carey crosses a line, impacting all of their relationships. 'Splitsville' is scheduled to release in theaters on August 22.
