Billie Eilish admitted that he used a stunt double in his performance at Coachella. In an interview with Apple Music 1, the singer explained that a dancer from her corps de ballet performed at the beginning of her show.
“I dressed her in a show look that I had worn before. We took a black wig and we put buns on it and we gave her a mask and sunglasses and she wore my shoes and my socks. I put her at the back of the stage and she stayed there while the lights came on and everyone thought it was me. And no one ever knew she wasn’t me, literally no one did. And while she was up there, I put on a big black coat and a traffic vest and a hoodie and just glasses,” she joked.
Videos of her performance show the doppelganger at the back of the stage as the singer gives an introductory sequence with excerpts from the tracks Oxytocin and Happier Than Ever. However, the person’s face isn’t visible until approximately two minutes into the set, at which point their 2019 single Bury a Friend starts playing.
