Sia performs at SeriesFest in Colorado (June 22, 2016)

Sia was on stage for the opening night of SeriesFest in Colorado, when the wind picked up and exposed her left eye, nose and mouth for the first time years.

She continued singing through the inadvertent reveal, appearing either unaware that it happened (her eyes were closed) or not caring as much as people thought she might.

In a December visit to “The Ellen DeGeneres Show,’ Sia explained her desire to remain hidden: “Well, it’s so that I can go to Target and buy a hose if I want to. Or if I’m in need of a restroom and I can’t find one, I could go by the side of the road.”
