When Justin went into the mall, hundreds of female fan reportedly crowded around the HIM!as he attempted to try on new frames.Umm,I'm not totally sure why he was in a mall shopping sales? He’s got lots of money,Jk jk!!! XD

"There were a lot of vases being broken and people climbing over other people and a lot of screaming," one fan told the newspaper.
