This morning Ariana Grande and Big Sean's reps sent out a press release exclusively to US Weekly stating that the couple would no longer be dating. Now, last week there were stories and rumors everywhere that Big Sean was pissed about Ariana doing a show with Justin Beiber where the two got a little too close. The reps have stated the break up is due to the fact that the couple will be seeing less of eachother when they go on tour next year. There's a huge possibility that Big Sean got a little too insecure and they decided it was best to call it quits because he can't be in her presence 24/7. Just a thought..
