Justin Bieber – Fan Tripping At Concert Not My Fault!!!

EXCLUSIVE

Justin Bieber is pulling the "what do you mean?" card on a New Jersey woman who's suing him after she tripped on a loose cable at one of his concerts. 

Bieber's camp is calling BS, saying there were NO electrical cables lying anywhere around where Sandy Ricketts was standing, during the 2013 "Believe Tour in Philly". They say if she hurt herself she has her own clumsiness to blame. 

In Bieber's legal docs, there's also an interesting reference to the fine print on the concert tickets, which say fans assume the risk of injuries when they attend. 

Ricketts says she was hurt bad ... severe and permanent injuries including a broken shoulder, busted lip that required surgery and a sprained wrist.

Bieber and company are asking a judge to throw the case out.
