GUESTS staying in the same hotel as the Canadian singer Justin Bieber may find they have trouble getting enough sleep. Last month, phones in the London hotel where the 18-year-old star stayed didn’t stop ringing once as his fans tried to call him. According to The Sun newspaper, teenagers who wanted to speak to Bieber made more than 2,000 calls to the hotel in one week. They gave false identities, claiming (声称) to be his friends or relatives. “Justin’s fans are relentless – they will do anything to get near him,” a hotel source told the newspaper. “The phones in the hotel haven’t stopped ringing since he arrived.”
