Sia Leaks Her Own Nude Photo

For a long time, singer-songwriter Sia didn't show her face.

But it turns out she's quick to show her ass.

The 41-year old jumped on Twitter last night and shared a photo of her buck naked from behind. She did so to make sure the paparazzi who caught her without clothes wouldn't profit from their intrusion.

Do you have any interest in seeing that shot from the front?
