Once again, we didn't catch Sia on the screen, but it doesn't matter because she sounds FABULOUS!
This isn't the first time the singer decided to sing off camera so it isn't very surprising!
The talented singer-songwriter performed her hit Chandelier on Dancing With the Stars while Allison Holker and Maddie Ziegler danced for her!
It was definitely entertaining to watch!
Ch-ch-check out the performance piece (above)!!
