Amazing, no? And, of course, Sia performed with the help of "Dance Moms"-turned-music-video-star Maddie Ziegler, along with a few other young singers in matching blonde wigs and white cutout boxes.
Sia also announced on "Ellen" that she will be performing at the upcoming Grammy Awards, of which she is nominated in four categories (see the full list of nominees here). The Grammys air on Sunday, Feb. 8, at 8/7c on CBS.
