25 Hollywood Nude Photo Scandals

"Everyday is Christmas!" Sia tweets with nude invasive photo of her backside.

Sia kicked off the holiday season by giving her fans a look at her naked butt in an effort to thwart a photo agency from profiting from the image.

The notoriously private singer, who regularly hides her face with masks, wigs and paper bags in public, shared the paparazzi photo -- credited to FameFlynet Photos -- on Twitter Monday evening.

"Someone is apparently trying to sell naked photos of me to my fans," the "Titanium" singer tweeted. "Save your money, here it is for free. Everyday is Christmas!"

"Everyday Is Christmas" is also the name of her upcoming holiday album, dropping Nov. 17.

The photo shows the nude backside of the 41-year-old singer, who appears to be outside some kind of private residence. (Well, not that private.)

Since the photo is owned by an agency, TooFab can't embed the media from Sia's tweet, but if you're itching to see what she looks like in the flesh, click the link below for your early Christmas present.
