Justin Bieber Hotel Prank

Daily Mail: The mania which surrounds him has left many of the (even only very slightly) older generation bemused. But the hysteria which greeted 'Justin Bieber' on one outing in Switzerland was truly unbelievable.

A clip posted on video-sharing website YouTube shows how a group of screaming 'beliebers' raced towards a Zurich hotel, thinking their idol was on the rooftop. Within seconds of his appearance, the volume of screams intensify and hundreds race towards the hotel.

However, from the giggles and gasps of disbelief from what appear to be laughing hotel staff, the star is, in fact, an imposter, dressed in shirt and baseball cap. He waves to the scores of girls and holds his arms aloft, evoking more screams, then disappears down a stairwell.

The short clip was uploaded this week, following the 17-year-old star's recent visit to the country. The teenager tweeted while he was in Zurich: 'a fan has already brought me a swiss army knife. im ready.'

Later that day, however, he seemed less happy with his stay: 'that was the longest bus ride EVER ...or at least it felt that way.'
