Golf has been known as a non-contact sport. Unfortunately for Justin Timberlake, that wasn't the case. While he was walking through a crowd at a golf tournament in Nevada, an unidentified man slapped Justin in the face over the weekend. It was so quick that TMZ, which reported the incident, had to put the video in slow motion so that we could all catch the moment. "Bro, why would you do that?" Justin yelled at the American Century Celebrity Golf Championship at Edgewood Tahoe Golf Course on Saturday (July 23). After the quick reaction, Justin kept it moving. As for the guy, who was being drunk and belligerent. That man ended up being arrested for disorderly conduct.
