The actor and singer is back to eating meat after a time as a vegan. The actress reportedly finds the vegetarian diet difficult to maintain, especially as she loves cooking for her boyfriend. Making the same dishes for both herself and her boyfriend is easier for Drew than cooking separate meals. Drew Barrymore has joined a long list of famous people who have tried to follow a vegetarian diet. Natalie Portman famously gave up her vegan lifestyle when she became pregnant.
