We keep hearing story after story about how Justin Bieber is such a brat! Recently Justin guest starred on CSI and some of the actors on the show revealed that Justin is "kind of a brat...he locked one of the producers in the closet and he put his fist through a cake!" Ummm....srsly Biebs?!
Ugh, it seems like Justin has really let fame go to his head and we don't like it at all! (nydailynews)
