YOU cannot blame Justin Bieber if his fans scream so damn loud you go deaf, and you definitely can not sue him over it either at least according to legal docs filed by Bieber’s lawyers. TMZ broke the story ... a mom named Stacey Betts slapped Bieber with a $9.23 million lawsuit, claiming her hearing was severely damaged at a 2010 concert when the Bieber "enticed the crowd” into a screaming frenzy.Bieber wants the case dismissed due to lack of facts.According to the documents, there’s no way Bieber could have known "pointing to a crowd” would cause a so-called "sound blast” -- and Betts’ suit also fails to allege Bieber has any duty to stop fans from making noise.
