We know Sia isn’t so keen on showing her face in public (so, hey, why not record a pop album?), but her GRAMMY performance tonight was some other-level shy stuff.

Sia’s performance of “Chandelier” began with a wigged Kristen Wiig (yes, really) lip-synching the song on a set that looked like a cross between a living room and antique store (with maybe a dash of Pee Wee’s Playhouse). Wiig was joined by another mini-Sia: Maddie Ziegler, the 12-year-old star of Sia’s “Chandelier” video.

The two chased each other through the makeshift room while a third Sia (this time the singer herself?) stood facing a wall.

Well during last year’s GRAMMYs, the actual Daft Punk bandmembers were possibly not the guys in the Daft Punk suits during their “performance,” so maybe this charade wasn’t so unusual after all.
