If you’ve seen any of Sia’s music videos or performances, then you’re familiar with a few things: one, that she never shows her face. Two, that she’s been using ‘Dance Moms’ star Maddie Ziegler as her mini-dancing-me. And three, that her videos feature passionate, inventive dance moves. A Sia performance is a real treat, and the one she put on at the Grammys last night was particularly delightful, as former ‘SNL’ star Kristen Wiig joined Sia and Ziegler on stage for an energetic rendition of “Chandelier.”

The sort of dance choreography Sia’s been featuring in videos like “Chandelier” and “Elastic Heart” is pretty much right up Wiig’s alley—it’s expressive and sort of wacky, both fun and emotional at the same time. In the video above, you can watch Wiig and Ziegler perform a dance very similar to the one Ziegler performs in the official “Chandelier” video, though this time around the song takes on a new layer, as Ziegler acts as the mini-version of Wiig, and the two dance-argue (is that a thing? I guess that’s a thing now) throughout the staged apartment setting.

Wiig performs beautifully, and we’d love to see her dance with Sia again. And this isn’t the first time Sia’s used a famous actor for her work—she recently cast Shia LaBeouf opposite Ziegler in the somewhat controversial video for “Elastic Heart,” and she had Lena Dunham dance during a performance of “Chandelier” on ‘Late Night With Seth Meyers.’
