PHOTOS: Sia's wig blew off at a concert and totally REVEALED her face!

Though Sia's face is displayed prominently on her early albums, it's been in hiding for the past few years. She's taken to featuring other artists like Maddie Ziegler in her music videos, and often chooses to stand upstage when she performs. Oh, and that now-iconic wig is always firmly in place.

But at a concert on Wednesday night, the wig was no match for a strong gust of wind that revealed her face. (Spoiler alert: it looks pretty much the same as it does on her album artwork from past years...)
