When Justin was on his believe tour he had hit his head HARD on a glass door when he was going out on stage. After he preformed he was going down some stairs to get to his car, when he got down the first flight of stairs he had got knocked out from a concusion for 4-5 min. The next day Justin said he has a headache. Also Justin had gotten stuck on a elevator with it packed full of people. After 3 min they finally got off but Justin is highly clostraphobic. So he over exaggreated a lil bit after he got off Justin said- "We where stuck in there for 3 hours" he said jokenly. For some reason glass doors and windows do not like him neither do elevators.
