Tens of thousands of Justin Bieber fans converged on the Oslo Opera House in Norway today when word spread that the pop sensation would be performing a free mini-concert there.
In fact, the frenzy has become so intense that local authorities are reportedly trying to get Bieber to take the stage sooner than later.
Bieber himself has tried to restore order in the area by tweeting out to his followers.
"for the show to happen u must all listen to the police," he wrote just hours ago. "we are all concerned for your safety and i want what is best for u. please listen."
After Oslo, Bieber is scheduled to make his way to Paris, Milan, Verona, Madrid, London, Cologne, Berlin, Mexico City, NYC and Toronto.
Rest of the world, consider yourself warned.
