57th GRAMMY Awards - Show
Eagle-eyed viewers may have noticed a familiar face performing with Sia at the Grammys on Sunday night: Kristen Wiig.

The "Saturday Night Live" alum helped 12-year-old dancer Maddie Ziegler recreate the singer's "Chandelier" video for the Grammy broadcast, donning a platinum wig and performing an interpretive dance. Sia, who's become rather secretive in recent years, declined to face the audience for the song, instead standing against a wall while Wiig and Ziegler took center stage.

There's no full (legal) video from the event online yet, but check out a short clip of the performance -- along with some photos -- below. Maybe if this whole "Ghostbusters" thing doesn't pan out, Wiig can take up dancing full time?
