Why was Justin Bieber crying on stage?

Justin Beiber cried on stage because he was sad.

I cried at Justin's concert because he is so hot and his songs are amazing, and because I actually could not believe I was like meters away from him and seeing him in real life not on YouTube or anything!

Answer 3

Justin crys a lot. he crys mostly at concerts like down to earth, because its about his parents splitting up, that should be me is because so many girls split with him and he loved them and favorite girl because he loves his fans so much and he is so happy that he is living his dream. it's OK that he crys because that means he's not afraid to show his emotions. he is a great guy and you should love him a lot.

Answer 4

Justin Bieber threw up on stage in Glendale, Arizona apparently because he drank too much milk before he went on stage. The reason he gave was a ligitimate one, most people thought it was because of alcohol; but Scooter told everyone weeks before that, Justin won't allow anyone to drink alcohol before they go on stage so when he says that he drunk too much milk that was probably the case.
