NJ woman sues Justin Bieber, and not over the music

A New Jersey woman is suing pop star Justin Bieber, saying she broke her shoulder, damaged her teeth and needed surgery for a cut in her lip after tripping over electrical wires at a show.

But TMZ reports Bieber is "calling BS, saying there were NO electrical cables lying anywhere around where Sandy Ricketts was standing" during the 2013 concert in Philadelphia.

Ricketts is asking for $50,000. Bieber's peoplre are asking a judge to toss the case out.

TMZ also notes the Bieber camp's filing points out fine print on concert tickets that say attendees assume the risk of injury.
