The Australian vocal power house Sia, who has an unknown identity as she goes around covering her face with wig talks on why she conceals her face on the Ellen Degeneres show
The Chandellier singer insisted she keeps her face obscured so she can shop in peace, or go to the loo "on the side of the road".
She said: "Well it's just so that I can go to Target and buy a hose if I want to. Or if I find I'm in need of a restroom, I can go in the side of the road, no one would be following me with a camera trying to get a shot."
Ellen has seen her friend's face in private, and she tried to coax her into removing the wig and showing others the beauty hiding behind it.
"You're beautiful," she said. "Are you going to do it?"
Sia confirmed she will reveal her face in public one day, but insisted she is building "up to it".
She added: "I'll do it, I'm just working up to it, you know."
