In an interview with Vogue, Sia explained that she hides her face as a way to “have some control over my image”.

“I’m just trying to work out a way to be a singer and to create cool content,” she said at the time. “I’m willing to do that as an entertainer. But I’m not willing to give up my actual self.”

So, when someone began circulating invasive paparazzi shots of the singer, with the aim of selling them to the highest bidder, Sia reacted by taking back control and publishing the image herself to Twitter.

“Someone is apparently trying to sell naked photos of me to my fans,” she wrote.

Then, attaching one of the shots in question, the Chandelier singer continued: “Save your money, here it is for free!”

The post suggests that a picture agency (possibly FameFlyNet, as their watermark is on the image) is attempting to sell 15 images of the singer, including at least one of her nude.

“If you make the purchase, the image will be unblurred and you will receive an additional 14 images,” it promised.

Naturally, it wasn’t long before the masses were flocking to social media to praise the singer for her post.

“Iconic,” wrote one.

“What a queen,” added another.

And still one more said: “You’re amazing.”

However, because Sia is a savvy businesswoman, she didn’t stop there.

“Every day is Christmas,” she added, in a clear reference to her brand-new (and incredibly festive) new album of the same title.

And, just like that, Sia had channelled the invasive image into positive publicity for a project she is incredibly proud of: her first-ever holiday album.

So far, fans have only been able to wrap their ears around Santa’s Coming For Us, aka the lead track, but we already know that there are plenty more toe-tapping tunes to come.

Think Candy Cane Lane, Ho Ho Ho, Puppies Are Forever, Underneath The Christmas Lights, Snowman, and Snowflake.

Anyone else excited for the album’s release on 17 November?
