Sia visited the Ellen DeGeneres Show to perform her hit song “Chandelier” with the star of the song’s music video, Maddie Ziegler.

Sia & Maddie Ziegler Perform On 'Ellen'

Instead of taking center stage, Sia retreated into the background and faced away from the audience as she sang “Chandelier” live. Meanwhile, Dance Moms star Ziegler, whose performance in the music video contributed to its over 11 million views, took the spotlight. With an elaborate set that recreated the music video scene to work with, Ziegler wowed with the dark contemporary routine.

At the culmination of the performance, DeGeneres applauded both Ziegler and Sia, who remained in the corner of the stage, facing away. Zielgler and DeGeneres shared a group hug with the shy musician, who offered a “thank you” to the rousing cheers from the audience.

Sia, 38, generally likes to keep herself out of the spotlight and only appears in the music video in a portrait on the wall of the dilapidated house in which Ziegler dances around. Sia, who’s written hits for the likes of Rihanna and Beyonce, co-directed the music video with filmmaker Daniel Askill.

"Chandelier" is the lead single off Sia’s forthcoming album 1000 Forms of Fear.
