He hasn't exactly been keeping a low profile recently, becoming known for his 'pop brat' antics. And Justin Bieber was at it again on Thursday as he was photographed spitting over a hotel balcony onto a crowd of waiting fans. Showing just what he thought of the throng of adoring girls, the pop superstar can be seen hurling saliva over them ahead of his concert in Toronto as his amused friends looked on. After the disgusting act, the star seemed to be pleased with himself, turning to his group of admiring friends to laugh. His impressed pals joined in with the tearaway teen and then they all crowded around him as he took a snap on his phone. Seeing the reaction from his legions of loyal fans, Justin seems to get even more amused and starts filming them on his phone. Hordes of fans were seen gathered outside his Toronto hotel and were filmed by Bieber in the video. 'I wake up this morning to this :) best fans in the world #beliebers #sexyfans' he wrote alongside the footage.
