Watch Sia Perform 'Alive' on 'Ellen' -- But Does She Take Off Her Wig?

Warner Bros.
Sia and Ellen DeGeneres

Everyone's favorite child dancer has been missing from Sia's performances as of late -- but not anymore.

Fan favorite Maddie Ziegler hasn't been in any videos for Sia's recent releases, nor is she the young girl on the album cover. But just when all hope was lost, the Australian singer brought Ziegler back for a performance of one of her new singles, "Alive," from her upcoming album This Is Acting on Ellen. Sia -- or, rather, her legs -- are seen behind a large black dress nailed to the wall while she sings and Ziegler dances her typically erratic and emotional choreography.

Sia also sat down for an interview with friend Ellen DeGeneres, during which the pair discussed Sia's signature face-obscuring wig. The pop singer began wearing elaborate props and wigs to cover her face in public when she gained international recognition years ago. Sia teased Ellen that she began wearing wigs so she could "go to Target and buy a hose if [she] wants to" or if she needs to go to the bathroom, she "can go by the side of the road."

Eventually, the joke turned into Ellen declaring Sia was going to take her wig off and reveal her face. After several attempts to unpin the wig, holiday music began and it all turned out to be a ploy to transition into Ellen's Christmas giveaway.

Those disappointed by the duo's pranks will be relieved to know that a simple Google Image search will show plenty of pre-international-fame pictures of Sia's lovely face.
