This sure is a rare move for Sia.
Many of us wouldn't be able to recognise Sia if we ran into her in the local shop, and that's because she wants it that way.
She revealed to Ellen DeGeneres last year that she likes to keep her face hidden so that she could 'go to Target and buy a hose' if she wanted to.
After shooting to fame, she found it difficult to adjust and wished to keep some anonymity.
For some reason, that seems to have changed.
She has been photographed in Los Angeles without her wig that normally covers most of her face.
