London, Sep 20 (ANI): Actress Alicia Silverstone has stripped naked to encourage vegetarianism.

The 'Clueless' actress, who was voted sexiest female vegetarian in 2004, took off all her clothes for the 30-second TV commercial for the goveg.com campaign launched by the People for the Ethical Treatment of Animals (PETA).

The ad begins with Silverstone sensually pulling herself out of a swimming pool, carefully hiding her modesty with her arms.

It follows with soft shots of the star perched at the edge of the pool with her back to the camera revealing her butt and close-ups of her face.

The 30-year-old actress says over the film, "I am Alicia Silverstone, and I am a vegetarian", before insisting, "There's nothing in the world that's changed me as much as this. I feel so much better and have so much more energy. It's amazing."

Silverstone also appears in a poster for the campaign, in which she is seen sprawled on the ground in front of the pool, under the words: "I am Alicia Silverstone, and I am a vegetarian." (ANI)
