A windy Colorado night has disrupted Sia’s onstage anonymity.
The famously private singer was performing at the opening night of SeriesFest, when a gust of wind revealed her face.
But the show went on and the 40-year-old continued her performance alongside Dance Moms' star Maddie Ziegler.
Sia once told Nightline’s Chris Conley that she chooses to keep her identity private because she doesn’t “want to be famous, or recognisable. I don't want to be critiqued about the way that I look on the internet."
