During Chat chat Sia Explained why she likes to be behind the Mask
"I don't wear this unless there's cameras around. I just wear this to keep up a smidgen of protection. I was a vocalist for ten or eleven years to fair achievement. I was a heavy drinker and a medication fanatic and I calmed down and chose I would not like to be an artist any longer. I was starting to get a little bit famous and it was destabilizing," - Sia said in a meeting.
