I was surprised to hear this! Ariana Grande and Mac Miller have split up. The couple started dating in September of 2016 so they had been together for a while. Sources say that even though these two split, they're still the closest of friends. Apparently the main reason for the breakup was because of their busy schedules. I would imagine it's tough to maintain a relationship in Hollywood when you're constantly traveling. Glad it sounds like the two are still friendly though. Did you like these two together as a couple?
