Billie Eilish is teasing a new project with James Cameron.

During her sold-out night one Manchester concert on Saturday, in Manchester, Eilish revealed she is working on a 3D collaboration with James Cameron (Titanic, the Avatar films, Terminator franchise).

“So you may have noticed that there are more cameras than usual in here. Basically, I can’t say much about it, but what I can say is that I’m working on something very, very special with somebody named James Cameron, and it’s going to be in 3D,” the singer told the crowd. “So, take that as you will and these four shows here in Manchester, you and me are part of a thing that I am making with him. He’s in this audience somewhere, just saying. So don’t mind that, and also I’ll probably be wearing this exact outfit for like four days in a row.”

Details for the project are currently unknown. It’s also not been revealed if her brother and longtime collaborator, Finneas, will be involved.

The “Birds of a Feather” singer’s past film credits include the 2021 documentary Billie Eilish: The World’s a Little Blurry, directed by R.J. Cutler and Happier Than Ever: A Love Letter to Los Angeles, the 2021 concert movie. Eilish is currently touring her third album, Hit Me Hard and Soft.

As for Cameron, his next film is the highly anticipated Avatar: Fire and Ash, which is slated to release on Dec. 19. The runtime for the film will apparently be longer than The Way of Water, which was more than three hours long.
