Dhanush and Mallika pipped Vivek Oberoi, Vidya Balan, Sonu Sood, Shahid Kapoor, Amitabh Bachchan, Hema Malini and Kareena Kapoor to top the list, released Friday by the animal rights organisation.
"If I had to pick the very best thing about being vegan, it's my clear conscience," Sherawat said in a statement
Dhanush, whose song "Kolaveri Di" became an online sensation, said: "Being a vegetarian always made me feel healthy. I've always felt light. Every time I sit down to eat, I'm helping the environment. I'm proud to be a vegetarian. Go PETA, go green."
Last year saw Bollywood actress Vidya Balan and former union minister of state for external affairs Shashi Tharoor topping the list
Though she had to give away her sexiest vegan throne to Mallika, that doesn't make Bebo least important.
Kareena switched to vegetarianism all for the love of her then beloved Shahid Kapoor. Though both have gone separate ways, Bebo still religiously follow those 'good lessons' she learned from Shahid. Shahid also made it to top 10.
