Think all vegetarians are scrawny, pasty, mousy types? PETA is about to prove you way wrong!

The critter-friendly organization has named actress Olivia Wilde the Sexiest Vegetarian of 2010.

"Animal lover and activist Olivia Wilde proves that being vegan helps one shine from the inside out," PETA writes on its Web site.

"She has saved lives on Fox's hit show 'House' and has saved the lives of animals off-screen by choosing a vegan diet. Going vegan saves the lives of about 100 animals a year!"

The va-va-vegan explains on her Web site that she adopted the lifestyle mainly because she wanted to boycott torture factories, and adds, "I am also way happier when I eat a plant-based diet, and I feel about a thousand times more energetic."

Of being named this year's Sexiest Vegetarian -- alongside "The Biggest Loser" trainer Bob Harper ("a dude who disproves the silly lie that vegans cant be strong" says Wilde) -- the beauty, who appears in the upcoming "Tron: Legacy" and next year's sci-fi fantasy "Cowboys & Aliens," writes, "I am really honored, and very inspired to continue living the vegan lifestyle that has been so good to my body, my animal friends, and the world we live in. So thank you, PETA, and thanks to all who voted for me!"
