The results are in—and actor Olivia Wilde and NBC's The Biggest Loser trainer Bob Harper have been crowned the Sexiest Vegetarian Celebrities of 2010!

Animal lover and activist Olivia Wilde proves that being vegan helps one shine from the inside out. 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! Olivia explains, "Beyond my desire to boycott the torture factories, I am also way happier when I eat a plant based diet, and I feel about a thousand times more energetic." Whether she's helping animals and the environment or starring in upcoming films like Tron and Cowboys & Aliens, we can't wait to see more from Olivia.

Bob Harper whips people into shape on NBC's The Biggest Loser and relies on a vegan diet to keep him in top form. "I enjoy living a plant-based diet because it makes me feel clear headed and strong, not to mention my genetically high cholesterol dropped more than 100 points," says Harper. "That was all the motivation I needed.". In addition to an animal-friendly diet, Bob showed his love for animals by adopting an adorable pooch he named Karl.

They may choose to go vegetarian to improve their health, help end climate change, or avoid contributing to the inexcusable cruelty to animals on factory farms and in slaughterhouses, but one thing's for sure: All the vegetarian celebrities have won both our hearts and the hearts of animals.
