Emma Watson has posed for her first ever nude shoot, and it's for a good cause, of course.
The grown-up Harry Potter star got her quidditch kit off for photographer friend James Houston to raise funds for the environmental organisation Global Green USA.
Emma is just one (the most famous one) of the environmentally conscious celebrities and models featured in the photo book Natural Beauty, which will "celebrate the beauty of nature and raise funds for Global Green USA, supporting a global shift toward a sustainable and secure future".

The 22-year-old also makes a very brief appearance in a behind the scenes video of the project. Blink and you'll miss her though...
