She was joined at the star-studded event by her brother and longtime creative partner, Finneas O’Connell, who stayed close as they greeted guests and photographers.

While Billie is not connected to the Avatar franchise itself, she is currently working with Cameron on a separate project that has fans buzzing. The two recently co-directed Hit Me Hard and Soft: The Tour (Live in 3D), a concert movie based on Billie’s latest world tour. The film is scheduled to hit theaters on March 20, 2026.

With her 3D concert film on the way and her continued creative partnership with James Cameron, Billie Eilish’s appearance at the Avatar: Fire and Ash premiere felt less like a surprise and more like a celebration of what’s next.
