Telephone lines at Justin Bieber's London hotel have been jammed by more than 2000 calls from fans.
Teenagers desperate to speak to the Boyfriend singer - who arrived in London on Monday (local time) - have been trying to get through to his suite at the Royal Garden Hotel by pretending to be friends, relatives and even his personal stripper.
A source said: "Justin's fanbase 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."
