The photos show Watson all wet and steamy, adorned with only a flower. But it's for a good cause. The 22-year-old actress tweeted the news to her followers on Thursday.
A year ago, New York-based photographer James Houston began shooting nude photos of environmentally conscious celebrities and models. He says in a press release that his plan was to create a project to raise funds for Global Green USA, a nonprofit promoting sustainability. By featuring the former "Harry Potter" heroine, Houston said he aims to get younger people involved in efforts to preserve the planet.
"This project merges my longtime interest in the human form and my passion for the natural world," Houston said. "Natural Beauty was created to celebrate the beauty of nature, emphasizing what we still have versus what we have lost. I hope to raise environmental awareness among the younger audience through this project."
Houston will also release a 12-part webseries around the making of Natural Beauty, premiering March 25 on YouTube.
Watson will also shock fans with her next move. She'll star in the Sofia Coppola film "The Bling Ring,"based on the true story of young thieves who targeted celebrities like Paris Hilton, "The Hills" star Audrina Patridge and Lindsay Lohan.
She up for three awards for "The Perks of Being a Wallflower" at the MTV Movie Awards on April 14. Tune in to see if she takes home a Golden Popcorns she's nominated for.
