It looks like professional wall inspector Sia is 'premiering' something — likely her new single — on September 25. THAT'S THIS FRIDAY.
This here stencil drawing — showing a slightly modified wig — was shared on various social media outlets by her manager.
If you cast your mind back, the not exactly shit 'Chandelier' was also 'teased' in a similar manner at the start of last year.
EXCITING!
