Liam went vegan in 2015 after chatting to his ‘The Hunger Games’ co-star Woody Harrelson and reading up on animal welfare as well as suffering from health issues that forced him to go off red meat.
"After all the information I gathered about the mistreatment of animals, I couldn’t continue to eat meat,” he told Men’s Fitness in 2015. “The more I was aware of, the harder and harder it was to do."
"I have a lot of friends who are vegan. [Hunger Games co-star] Woody Harrelson was actually one of the original reasons I became vegan, because he’s been vegan for, I don’t know, 30 years or something. So, with the facts I was gathering, and then just how I was physically feeling, I felt like I had to do something different, so I adopted this vegan-diet lifestyle."
PETA also named singer Jhene Aiko as the sexiest female vegan celeb of the year.
