Justin Bieber reveals his biggest fear!
Justin Bieber has revealed his biggest fear in an interview with Glamour Magazine!
What do you think it is... snakes, spiders, maybe drowning?!
Nope, it's small spaces!
Which is pretty normal... none of us want to be caught in a tight squeeze.
However, it seems Biebs forgot all about this on the first night of his world tour!
During the performance of 'Mark My Words'... JB is seen singing whilst in a small box hoisted up in the air!
Wait, didn't you just say?!
Never mind... it looks awesome!
Check out the performance below!
