WATCH: Sia Sings, Lena Dunham Interpretive Dances for 'Chandelier' Live Performance on 'Late Night'

Last night (June 10), the world's most elusive pop star Sia showed off her vocals, if not her face in another electrifying performance of her single "Chandelier." The singer/songwriter teamed up with Girls creator/all around cool chick Lena Dunham and the duo offered up one weird-o beard-o live performance.

In an all white room, Sia laid face down on a lofted twin bed, Dunham mimicked the lyrics to the party-dangerous anthem, beginning the haunting gig by punching out the blank faces of four painted figures, which she then pushed down.

Dunham then did an interpretive dance of sorts across the stage, bopping on ladders, spinning, sucking her thumb and TP-ing the entire room, all while singing along to "Chandelier" with an intimidatingly blank stare.

Meanwhile, Sia was onstage, giving a loud and proud vocal performance of "Chandelier," once again proving you don't need to see her face in order to know she's one of the best singers in the game today.

This isn't the first time Sia teamed up with a interpretive dancer for a live performance of "Chandelier." Last month, the elusive pop star and Dance Moms star Maddie Zeigler on Ellen. For that performance, Sia his her face from the audience by turning her back, while Zeigler recreated the track's haunting music video.

"Chandelier" is the lead single from Sia's upcoming album, 1000 Forms of Fear, which is set to be released on July 8.
