Ariana Grande is currently dating Mac Miller. They are very cute together. When Ariana is around Mac, she is always laughing and smiling. Ariana even went to coachella to support Mac Miller. Even when fans catch videos of them together, they are always smiling. They seem like the perfect couple. I fully support Ariana in dating Mac, as long as she is happy. If Ariana (or anyone) is not happy in a relationship then they shouldn't be in that relationship. Happiana over Maciana. I am so happy for Ariana.
