Former Harry Potter actress Emma Watson has grown up. She recently teamed up with photographer James Houston for his upcoming book Natural Beauty. In it, Emma Watson poses nude/naked/topless for Earth Day. We have the photos here, and the full story why she did it. It's way better than the Earth Manure Calendar Photos

So what's this book all about? Hypable has the scoop:

Houston says Natural Beauty is “a photographic series inspired by the connection I feel to nature in my design work and in the environment. I shot some of the world’s leading celebrities and top models who are also environmentally conscious.”

The topless Emma Watson photos will appear during World Earth Week in April in New York and Los Angeles. The book will also debut the same week.
