That's one way to do it!

Sia caught wind that someone was trying to sell a naked pic of her to a paparazzi agency, so she decided to share the pic on her own Twitter to kill the sale. You've gotta love her!

"Someone is apparently trying to sell naked photos of me to my fans. Save your money, here it is for free. Everyday is Christmas!” she wrote, in reference to her upcoming holiday album.

She also shared the offer. "If you make the purchase it will be unblurred and you will receive and [sic] additional 14 images," the person wrote on the image watermarked "Client Preview."

What we wanna know is how the singer caught wind of this?!
