Justin Bieber sued for $9.23 million by a fan’s mother!

No, he didn’t knock up her daughter. 

But, Justin‘s screeching tween fans prove once again to be a dangerous liability, and this time a very expensive one. Biebs is being slapped with a lawsuit by an Oregon woman who claims that she suffered extensive hearing damage by shrieking fans at one of his concerts.

In the suit, filed Tuesday in U.S. District Court in Oregon, Stacey Wilson Betts claims that she attended a July 14, 2010, Bieber concert with her daughter at the Rose Quarter in Portland.

This is Justin’s first lawsuit by a mother, other than one claiming to be his baby mama.

According to the woman, the injury occurred when Biebs “climbed into a heart-shaped, aluminum/steel gondola and was pulled out over the crowd.” The lawsuit says Bieber then “enticed the crowd into a frenzy of screams by continuously waving his arms in a quick and upward motion.”

Unfortunately, according to Betts, “the gondola acted as a sound conductor, creating a sound blast that permanently damaged both of my ears.”

Betts claims that, because of the alleged incident, she now suffers “hearing loss, severe tinnitus (piercing ringing 24/7) and hyperacusis (an oversensitivity to certain frequencies) in both ears.”

The lawsuit, which also names Bieber’s record label Island Def Jam, concert promoter AEG Worldwide, and Vulcan Sports and Entertainment, which owns the Rose Quarter, is seeking $9.23 million in damages, plus court costs, attorneys’ fees and other expenses related to the suit.
