Sexy Shot: Paris Goes for the Gold

Paris Hilton hasn't exactly made a habit of being fully clothed. And judging by the celebutante's latest modeling gig, it doesn't look like you'll be seeing her dressed conservatively (if at all!) any time soon.

The Simple Life star bares it all, underneath a few coats of gold paint in a new ad campaign for Rich Proseco. The shots, some of which we can't post here, show the hotel heiress sprawled out on the desert — but it's all for a good cause, of course.

The shots will promote the Rich Water Foundation, which aims to provide clean drinking water for people in need around the world. The foundation was set up in Berlin, Germany, by Paris and the inventor of the Rich Prosecco drink, Guenther Aloys.
