Sia performs her hit song "Elastic Heart" with a special dance performance by Derek and Julianne Hough on the two-hour Season Finale of "Dancing With the Stars" on May 19, 2015. 

Tuesday night (May 19) marked the season finale of Dancing With the Stars and not only did viewers find out who the winner of Season 20 is, but Sia also stopped by to give another unexpected performance.


First up, Rumer Willis went home the champ this season, gaining not only bragging rights but also the show's famed mirror ball trophy. The actress, and her pro dancer Valentin Chmerkovskiy partner, beat out musician and Glee actor Riker Lynch as well as former United States Army soldier Noah Galloway.

As for Sia's performance of "Elastic Heart," the singer, of course, appeared with her face disguised as siblings Derek and Julianne Hough served up enough dancing theatrics to keep everyone entertained.

Featuring Derek and Julianne mini-me's, as well as the dancers themselves, the performance was an emotional interpretive dance. While the two sets of dancers performed in mirroring dances, Sia sang in the back of the stage, narrating their on-stage struggles.
