Australian singer Sia has leaked a nude photo of herself after she claimed the revealing image was being sold online.
The musician - who often obscures her face with masks or paper bags - has been labelled a "hero" by fans over the move.
The photo shows the 41-year-old pictured naked from behind.
Alongside a screengrab of the photo, she tweeted: "Someone is apparently trying to sell naked photos of me to my fans. Save your money, here it is for free. Everyday is Christmas!"
Her last line is hilariously on-message as her new album, "Every Day Is Christmas" - a collection of original holiday songs written by her and Grammy Producer of the Year Greg Kurstin - is out next Friday.
The presence of the two tweets at the top of the singer's feed makes for a comic contrast.
Fans on Twitter lauded her approach to combating those trying to profit from the nude photos.
