ooh la la 120 Report post Posted March 6, 2015 i'm not down with the kids so i don't know anything about justin bieber. but i was wondering why celebrities seem to hate him so much from what i read and hear.what did he do to deserve such hate is there something i don't know about. cos why would a grown man such as seth rogan have such hate for him i mean i understand if you don't like the music but to actually be mean to a person personally is weird.there are loads of big headed mean celebrities out there who don't get as much hate.
