Bieber Fever is plaguing the European continent at an all-time high. Just one month after crazy fans mobbed Justin Bieber at Heathrow Airport in London, Bieber mania hit Oslo, Norway, Wednesday night in anticipation of the 18-year-old pop star's free concert at the city's Opera House. It got so bad that "about 15 girls passed out" in the chaos and the police were involved. "Norway, please listen to the police. I don't want anyone getting hurt. I want everything to go to plan but your safety must come first," the wise, wise Bieber wrote on his Twitter page.
NORWAY - please listen to the police. I dont want anyone getting hurt. I want everything to go to plan but your safety must come first...

Earlier in the day, Bieber was crouched in his car as a group of screaming teenage fans chased after him. This is not the first time Bieber has caused rapid-fire mania, of course (nor likely the last): Concert cancellations, mass hysteria, and incessant sobbing now seem to be the routine side effects of super-stardom. Check out our gallery of some of the most ridiculous, high octane-screaming Bieber Fever moments, below.
