The rapper announced that he and his superstar wife are giving up eating foods made with animal products earlier today, writing, "Psychologists have said it takes 21 days to make or break a habit. On the 22nd day, you've found the way. On December 3, one day before my 44th birthday, I will embark on a 22 Days challenge to go completely vegan, or as I prefer to call it, plant-based! This all began a few months back when a good friend and vegan challenged me to embrace a 'plant-based breakfast' every day. It was surprisingly easier on me than I thought."
