Sia has turned the tables on intrusive paparazzi after discovering a naked picture of her was being sold to her fans online. Instead of taking legal action, the Australian artist simply posted the picture in question to her social media accounts.

Sticking a big middle finger up to the photographer and agency behind the long-range photo, Sia wrote: “Someone is apparently trying to sell naked photos of me to my fans. Save your money, here it is for free. Every day is Christmas!”

The post suggests that the picture agency, FameFlyNet, according to the watermark on the photo, was attempting to sell multiple images of singer, including at least one of her nude. It's not clear to whom the snaps were offered, but Sia suggests it was to her fans — naturally, they reacted with glee to see the singer get one over the paparazzi.

Despite being one of the most successful artists in the world who has sold millions of copies of her own work as well writing songs for Rihanna, Beyoncé and others, Sia has always been incredibly protective of her privacy. She regularly obscures her face with masks, wigs, hats and even paper bags when in public.
