Sia & Lena Dunham Perform "Chandelier"

Sia avoided hair and makeup during her performance of “Chandelier” on Late Night with Seth Myers Monday night.

She featured Lena Dunham as her muse who, under the circumstances, did a decent job galloping and flailing about. Plus, the “Girls” star was lookin’ real comfortable in that blond wig.

Props to Sia for singing on her belly.
