Billie Eilish kicked off the 45th season of Saturday Night Live this weekend with a performance of her first no. 1, "bad guy." Instead of sticking to the formula that most musical guests follow, Eilish opted to switch things up. Borrowing some inspiration from Fred Astaire's 1951 film Royal Wedding, Eilish had the SNL soundstage shrunk into a rotating box with a camera attached to it. The result was a performance that had her standing on the ceiling.
In a new video, Eilish reveals the mechanics behind the performance — from conceptualizing the setup with a tissue box on her living room floor, to building the set, to the day of show. Check out all the behind-the-scenes footage below, and watch the "bad guy" performance above.
