The week of  Justin Bieber  in London was really long, and despite rumors, paparazzi problems and criticisms faced by Canadian, she finally came to an end, but still making headlines in tabloids and websites around the world.

This time, the American tabloid U.S. Weekly  ran a story with exclusive, justifying some of the week’s events Bieber, after information from a source close to the singer and secret.

A source close to the singer has an explanation for at least some of the bizarre behavior of Bieber.  ”Gas mask that Justin has used while walking around London is a joke between friends, but people are starting to take this seriously,”  a source told Us Weekly. “Justin’s friend, Julian Keyz [ a young songwriter / producer also known as Julkeys] , also uses a mask to pretend that he is Justin and deceive people, since they have the same height. ‘

“All friends take turns using it as a joke to evade photographers,”  the source continued:  “It is not something serious, they’re just having fun with it for London.”

The 19 year old singer was spotted wearing a strange mask first few weeks ago, while shopping in London. He donned the disguise for the second time on Wednesday, March 6, at the exit of the renowned restaurant Mr. Chow’s.

Just a week before, the singer of “Boyfriend” impressed people for another reason – he dressed with a set of leopard-print pants, a cotton jacket with blue notes and drawings of coiled yellow, and a yellow cap with silver stones.

Later, Bieber told directly to his fans why he dressed well, telling them that used the unusual visual as part of a bet with his buddy Ryan. “Ryan said, ‘You’re not going out wearing that,’ I said, ‘Look for me, ‘”  the joker wrote on Instagram. “Haha, very colorful. Next time, I’ll wear a black cap.”

On Tuesday, March 7, the singer has been hospitalized after fainting in the middle of her show at the O2 Arena. After getting off stage 20 minutes recovering, he returned to finish the show. Then the singer played their last show in London on Friday, March 8, same feeling ‘a little short of breath’.
