Justin Bieber was reportedly forced to leave his London hotel after fans got hold of his room number.
The Baby singer was staying in a luxury hotel while he was in town to perform at Capital FM's Summertime Ball at the weekend, and according to The Sun the teen hearthrob's room details got out.
The hotel was inundated with so many calls from excited fans - dubbed "Beliebers" - that the phone lines crashed, and Justin decided to move to another hotel.
Justin has been touring Europe, leading to chaotic scenes. Earlier this month there was a stampede in Oslo when Justin offered free tickets to see him perform at the city's Opera House. Forty-nine fans were reportedly hurt in the rush for tickets and 14 were taken to hospital for treatment.
The 18-year-old was then chased by fans on speedboats as he left the concert by boat.
The star is now off to Mexico where he will perform a free show.
A "tween" squatter encampment has already sprung up in Mexico City as Beliebers queue to make sure they are as close to the stage as possible.
Authorities said they would have more than 5,000 police on hand for the concert, helping keep order around barricades and checkpoints meant to prevent a dangerous crush of fans.
