Justin Bieber has opened up to Cosmopolitan with a bunch of facts fans don't know about him already, and one of them made us totally nod our heads in agreement! Justin spilled his biggest pet peeve, and we bet many of his beliebers have the same one!

Justin explained that what he can't stand most is "waiting on slow internet." We feel you Justin!
