Justin Timberlake Reacts on Stage to Fan Giving Him the Finger [VIDEO]

Justin Timberlake's 20/20 Experience concert made a stop in Philly late last year. And at one point, JT noticed someone in the audience giving him the finger.

His on-stage reaction was priceless.

Why would someone pay so much money to be in the second row of a JT concert just to flip him off? Desperate cry for attention? Probably. But, Justin addressed the gesture on stage with humor and the typical JT smoothness.
