On Monday night, Sia performed her hit song "Chandelier" -- which happens to be one of TIME's 25 best songs of the year (so far) -- live on Late Night with Seth Meyers. Though Sia has typically performed the song with the video's star, child dancer Maddie Ziegler, for her latest set she went with a different Girl -- Lena Dunham.
While Sia lies face down on a bed and sings, Dunham performs a modern dance to the song about a girl who loses herself in partying. Though her lip-syncing leaves something to be desired, Dunham is a captivating presence on stage as she dons a Sia-inspired blonde wig and executes some serious spins.
Sia's upcoming album, 1000 Forms of Fear, is due out July 8.
