Jason Momoa and Adria Arjona appeared to take another significant step in their relationship this week as the actress joined the Hollywood star and his two children for a rare family outing at the Supergirl premiere in London.

The 46-year-old actor was accompanied by daughter Lola, 18, son Nakoa-Wolf, 17, and girlfriend Adria, 34, as they posed together on the red carpet on Wednesday evening. According to reports, the group smiled for photographers during the high-profile event, offering a rare glimpse into Momoa's family life.

The appearance immediately sparked interest among fans, with many viewing the outing as a sign that Arjona has become an increasingly important part of the actor's inner circle.

While Momoa and Arjona have attended several public events together since confirming their romance in 2024, appearances involving his children remain uncommon, making the London premiere particularly noteworthy.

Adria Joins Jason's Children for a Rare Public Family Outing

Momoa, who shares Lola and Nakoa-Wolf with ex-wife Lisa Bonet, has long been known for keeping his family life relatively private despite his global fame.

The actor proudly posed alongside his children and Arjona as they arrived at the premiere, creating one of the most talked-about celebrity moments of the evening.

The quartet appeared relaxed and comfortable together as they walked the red carpet, fuelling speculation that the relationship between Momoa and Arjona continues to grow stronger.

For many celebrity couples, public appearances involving children are often viewed as a meaningful milestone, particularly when family members are rarely seen together at major events.

Fashion was also on full display as the group stepped out for the London premiere. Momoa showcased his signature rugged style, while Arjona looked effortlessly elegant for the occasion. Lola and Nakoa-Wolf also embraced the evening's glamour, completing the family-focused look.

Although the event celebrated the upcoming release of Supergirl, much of the attention surrounding Momoa centred on the personal significance of those who accompanied him.

Romance Continues To Go From Strength to Strength

Momoa and Arjona first sparked dating rumours in early 2024 before the actor publicly confirmed their relationship in May of that year through a series of photographs shared from a trip to Japan, as People reported.

The actor referred to Arjona as 'mi amor' in the social media post, effectively making their romance public for the first time.

Since then, the couple have attended a number of high-profile events together, gradually becoming more open about their relationship while maintaining a relatively low profile compared with many Hollywood pairs.

The Supergirl premiere, however, stood out for bringing together some of the most important people in Momoa's life.

By appearing alongside Lola and Nakoa-Wolf on the red carpet, Arjona appeared firmly integrated into the actor's family circle. While neither star has publicly described the outing as a relationship milestone, the rare family appearance is likely to fuel further speculation about the seriousness of their romance.

As cameras flashed outside the London venue, the evening became about more than just another blockbuster premiere. For many fans watching, it appeared to mark the latest chapter in Momoa and Arjona's relationship, and perhaps the clearest sign yet that their bond continues to deepen.
