Shania Twain and Carrie Underwood have held the title, but this year it belongs to Kellie Pickler!
Why did Kellie go vegetarian? She told People magazine "One night I couldn't sleep and I was up just Googling random stuff and I'm like, 'Hmmm, PETA.' I saw all the videos and I just thought it was horrible ... it really bothered me and so I will not eat meat." She's friends with Carrie and Carrie helped her give up meat (which neither thought she could - lol)
