Billie Eilish performed her new single “Your Power” in a segment that aired on Monday’s episode of The Late Show with Stephen Colbert.
The singer was joined by her brother and collaborator FINNEAS on guitar in a desert setting evoking the track's official video.
“Your Power,” released last month, comes from Eilish’s sophomore album Happier Than Ever, which is set to drop on July 30.
In a chat with Colbert, Eilish reflected on having to wear a wig while her hair was slowly being dyed blonde.
“I knew it would have these processing periods where it would look insane, and I didn’t want to look insane,” she explained. “But I needed something quick – so I literally ordered a Billie Eilish halloween costume wig on Amazon.
“It was awful. It was the ugliest thing I’ve ever seen.”
Eilish said she eventually replaced the "plastic" wig with a professional one. "The thing was, I wasn’t trying to play a prank on the internet," she explained. "No, I just looked f**king crazy underneath and I needed to look not crazy."
