We’d almost forgotten about Clueless star Alicia Silverstone (God we, like, TOTALLY loved that film). Anyway, she just got our attention again by taking her clothes off (heatworld always favours this way of communication. Unless it's the tramp that sits on the wall outside our house. We so don't need to see that). Aaaaanyway, Alicia has stripped off for an advert for PETA, extolling the virtues of vegetarianism. “My name is Alicia Silverstone, and I am a vegetarian,” she declares. Thrilling, we know. Thank God then, she goes on to emerge – completely starkers – from a swimming pool. PETA hopes the ad will help stop people eating animals in Houston Texas; the fattest state in America. We like seeing clothing-free celebs, but we're not entirely sure this will work…
