James Houston’s ‘Natural Beauty’ Features Stars in the Nude (PHOTOS)

A new book puts Emma Watson, Adrien Grenier, Karlie Kloss, and others in natural surroundings. See photos.

Emma Watson, Anja Rubik, Karlie Kloss, and more stars are posing nude for charity this month. They’ll be in a new book, Natural Beauty, that comes out with Damiani in April and brings together two of photographer James Houston’s greatest passions: “the human form and the natural world.” 

Watson poses with a flower at her mouth, model Arizona Muse holds her son, and Coco Rocha dances with blue fabric. “By celebrating the incredible beauty that exists in nature, my hope is that these images will inspire people to appreciate and value nature’s beauty,” Houston said in a statement. 

In April, the pictures will be displayed in an exhibition and auctioned off to raise funds for Global Green USA. (In the past, Houston’s Let’s Talk About Sex and Move for AIDS projects have raised more than $1.5 million.) See behind-the-scenes footage of Houston’s project here.
