Sia was the musical guest on Late Night with Seth Myers last night, but there's just one problem - she prefers to perform not facing the audience. To keep things interesting, she recruited Lena Dunham to perform an interpretive dance while she sang jam-to-end-all-jams "Chandelier" face-down in a loft bed. Lena, dressed up as Sia in a blonde wig and rocking some all-white-everything steez, embraced the challenge with some one-of-a-kind choreography. Check out the performance below, and remember, Sia's1000 Forms of Fear is out July 7th.
