Ariana Grande had to be included on this list of the world's most beautiful vegan women just to make sure I included some younger celebrities amongst this list of ladies. It took me a while to find a photo of her wearing even this much clothing, as she seems to prefer flaunting it all. But you've got to admit - she is absolutely adorable. At 21, she looks much younger than her age, and, thanks to her healthy vegan diet, she'll still be looking good for decades to come.

 

Though she says she was raised on meat and cheese, she's very outspoken about being vegan, and told one interviewer: "“I love animals more than I love most people, not kidding. But I am a firm believer in eating a full plant-based, whole food diet that can expand your life length and make you an all-round happier person.” Agreed, Ariana, agreed.
