Lena Dunham is no stranger to the music world. Her hit HBO series Girls is always up-to-date with the latest and greatest in indie, she's basically BFFs with Taylor Swift and Katy Perry and she debuted Miguel's latest jam on her show. Did we mention she's dating Jack Antonoff of fun. and Bleachers? She clearly knows what's up.
We can add another music bud to the list—the highly mysterious pop goddess Sia.
Sia was the guest on last night's episode of Late Night with Seth Meyers, where she brought out Dunham to perform the dance from her now-iconic "Chandeliers" video. Lena rocks a platinum blonde wig and moves in a contorted, experimental way while Sia sings, face hidden. Powerful stuff!
