Bieber`s fans jammed hotel line

London: Singer Justin Bieber`s fans went crazy when he checked into a hotel here -- more than 2,000 fans pretending to be his friends and relatives called and reportedly jammed the telephone lines of the hotel.

The 18-year-old arrived here Monday and since then fans have been trying to get through to his suite at the Royal Garden Hotel.

"Justin`s fans are relentless. They will do anything to get near him. The phones in the hotel haven`t stopped ringing since he arrived. Staff knew there would be pandemonium, but not to this extent," quoted a source as saying.
