Bieber fans were not impressed with his performance, or lack-there-of, at a concert in Stockholm. When fans wanted him to perform "Despacito" he replied that he did not know the words and that he wouldn't be able to perform it. Let's just say his fans did not take that lightly.
Some people are saying it was a shoe, others say it was a waterbottle or some other garbage. Whatever it is, it was chucked at the Biebs after he refused to sing "Despacito." He dodged it like a champ, though!
