I can't really seem to find many FAMOUS celebs who eat a meat-free or vegan diet. I would love to actually know if there is any out there?! Go post awayyyy!
A lot of those names are definite, but I find the best way to see if they're reliable is to find the name from that list you want to investigate as a guideline, then just type in their name and 'vegan' after it. That'll come up with sources.
