BIEBER fever? Not exactly.

The 18-year-old pop star is being sued for $9 million by a woman who claims her hearing was damaged at one of his concerts.

Stacey Wilson Betts says her hearing loss occurred after she took her daughter to the singer’s concert on July 14, 2010 in Portland, Oregon.

Stacey said it was incredibly loud inside the arena due to shrieking fans.

“I was injured by a sound blast that exceeded safe decibel levels. I suffer hearing loss, tinnitus and hyperacusis in both ears”, Betts claimed in the lawsuit, TMZ reports.

The suit alleges that Bieber “created a wave like effect of screaming by pointing into various sections of the arena.”

As a result, Betts claims she now suffers from tinnitus, which causes a constant pulsing, whooshing sound that makes it hard to sleep, along with other hearing-related damage.

The woman is suing Bieber, his label Island Def Jam Records, the concert promoter and the arena for a whopping $US9.23 million in damages.
