Justin Bieber was forced to cancel a press conference in Norway about a free show that he was about to perform because his fans went absolutely insane.

At one point multiple girls passed out, and Bieber even had to ask his fans to calm down on Twitter to help the police restore order.

Things did finally calm down, and the free concert eventually did happen.  This was part of the promotion of a new NBC Special called 'Justin Bieber: All Around The World' that will air on June 21st.
