Billie Eilish had a lovely evening.

After all, her boyfriend Nat Wolff was at her side as she celebrated the premiere of her new concert movie, Billie Eilish: Hit Me Hard and Soft The Tour, in Los Angeles on May 6. 

For the occasion—which marked the couple’s first joint red carpet appearance—Billie and Nat looked like two birds of a feather as they smiled, laughed and held each other close in front of cameras. 

For her part, Billie donned a black skirt, long white sleeve shirt over which she layered a green Ralph Lauren polo. She styled the look with red knee-high socks and white kitten heels. 

Nat, meanwhile, opted for a classic brown suit which he paired with a white button-down and black dress shoes. 

The movie, which she co-directed alongside James Cameron, chronicles the 24-year-old’s four-night run in Manchester, England, last year. 

Billie and Nat first sparked romance rumors in the spring of 2025, though this is the first official appearance they’ve made as a couple at an event.
