Sia gives out her nude photo 'free'Los Angeles, Nov 7 (AZINS) Singer Sia, after finding out that someone was trying to sell nude pictures of her, has shared one herself for "free".

On Monday night, the singer-songwriter claimed someone was offering naked pictures of her online. But the 41-year-old star decided to share the naked picture herself -- and also promote her upcoming Christmas album at the same time, reports mirror.co.uk.

"Somebody is apparently trying to sell naked photos of me to my fans," she wrote on Twitter.

"Save your money, here it is for free. Everyday is Christmas!"

The photo shows the nude star, who usually keeps her face hidden behind wigs for privacy, with her back to camera standing on what appears to be a balcony.

It appears to be a paparazzi photo but the origin is unclear.

The message underneath the photo reads: "If you make the purchase it will be unblurred and you will receive an additional 14 images."

Her fans soon flooded her social media channels with praise.
