Sia Dancing with the Stars Performance

by at .  Updated at .

Tuesday marked the final Dancing With the Stars results show of the season, which meant not only a champion crowned, but a long list of guest artists.

Among them? Sia, who stopped by to give another unexpected and powerhouse performance with the help of some of the DWTS cast members.

Before Rumer Willis was crowned the winner, Sia appeared with her face disguised as siblings Derek and Julianne Hough provided the theatrics.

Derek, a staple of the show's professional cast, and Julianne, his sister and former cast member/current judge, combined for quite the spectacle.

The interpretive dance was very "Sia," as the artist crooned in the back of the stage, narrating the on-stage struggles of the Hough mini-mes.

You can watch the emotional and powerful performance above.
