men myndigheterna hade inte räknat med en sådan stor folkmassa och berättade att Justin var tvungen att lämna platsen så att de kunde kontrollera det väntande fansen.
Det är inte första gången Justins popularitet har orsakat problem:
i november, en Justin CD signering i Long Island,  New York i kaos efter tusentals fans konvergerade i Roosevelt Field Mall i hopp om att fånga en glimt av honom.
I en post på hans Twitter.com blogg, skrev låten :

Paris is crazy! Had some interviews this morning with mags (magazines) and radio. Got to practice my French a little. But then the in-store (appearance)… there were thousands of kids at the in-store and the police were not expecting it. They reorganized the crowd and we got it going but after a little while the police stopped it and came in and said it was over and I had to leave. Sorry to any of the kids I didn’t get to meet….I love all of you for your support. To start my trip in Paris like this already, the love and the energy is amazing. Thank you so much.”
