Sia Performs Bird Set Free For Ellen -- But That DEFINITELY Isn't Maddie Ziegler Dancing!

Genius!
Sia is one of the best in the game right now, and her live performances are so unique!
And for her friend Ellen DeGeneres, she brought out the big guns — Maddie Ziegler!
Oh, wait. THAT’S not Maddie! LOLz!

No, for Bird Set Free, the singer/songwriter brought on a much older male dancer to bring out the emotion of the song.
Makes sense given that all the songs on her new album This Is Acting were written with other singers in mind.
Ch-ch-check out the very special performance (above) and get the album HERE!
