Gah! To think this hot young thing was once a frizzy haired Hermoine, swotting away in her spellbooks and hanging out with Ron and Harry. Well Emma Watson's all grown up but one thing's for sure; she's still well able to cast a spell, GEDDIT?

The Perks of Being a Wallflower who was recently rumoured to star in Fifty Shades of Grey has posed naked for a new book. And she looks bloody terrific. These photos aren't of the Kardashian variety, mind; they're as classy as they come. No trout-pout duck-faces here.

What's it all about? She's not just reveling in her own natural beauty, she's raising awareness for the environment. Well this just makes her even more likeable. The 22-year-old Harry Potter actress poses nude (and wet) with nothing but a few flowers in her hand. The images were shot by photographer James Houston. They'll appear in his new book, Natural Beauty (cue all the lads: "um, where can one purchase such a book?") as well as in an exhibition. Among the other celebs posing for the project are model Christy Turlington, Brooke Shields, Arizona Muse, Elle Macpherson and, randomly, Adrien Grenier. Not sure we want to see him doused in tropical flowers, do you?
