Billie Eilish just made her Saturday Night Live debut with a gravity-defying performance of "Bad Guy," and my head is officially turned at a 90-degree angle. The 17-year-old singer songwriter — who wasn't even alive the last time Woody Harrelson hosted, by the way — took to the stage in a matching rainbow graffiti t-shirt and shorts to mystify us with her hauntingly soothing vocals and basically throw herself a personal Halloween party à la Spider-Man. The flashing lights, topsy-turvy stage, and hypnotic vocals resulted in a sound that was altogether mesmerising. Watch Eilish's flipping awesome performance in the clip above!
