On Wednesday, he suffered a very humiliating knockdown in Cleveland and that was only one of the incidents that have sparked the concern of Justin Bieber's inner circle.

A source close to the 22-year old crooner said that "Justin's state of mind has been slowly deteriorating due to the constant stress of being scrutinized by the public and by his industry. He constantly feels like people forget that he is a human being and needs privacy, he is being overwhelmed by everything that has been going on lately."

The pop sensation posted an Instagram photo earlier this year that stated, If you happen to see me out somewhere know that I'm not gonna take a picture I'm done taking pictures," he wrote. "It has gotten to the point that people won't even say hi to me or recognize me as a human, I feel like a zoo animal, and I wanna be able to keep my sanity.  

Bieber continued by stating, "I realize people will be disappointed but I don't owe anybody a picture. and people who say 'but I bought ur album' know that you got my album and you got what you paid for AN ALBUM! It doesn't say in the fine print whenever you see me you also get a photo." 

Justin's close friends and family have reportedly suggested that he cancel his world tour after they noticed that the singer has been behaving erratically, a source close to Bieber revealed "They're concerned that he is slowly heading to a mental breakdown, we would see him being rude to fans one day and the next day he will be all lovey dovey with them, we don't know what he's going to do next because his mood erratically changes throughout the day."

Earlier this year he was rumored to have been dating Hailey Baldwin after the duo spent the New Years holiday together, he was later linked to Kourtney Kardashian and then Nicola Peltz who is also said to be one of Hollywood's Brats.
