At his show in Memphis last night, Russ and his team confronted a fan who allegedly threw ice at the artist as he was performing on stage. Like most people would react, Russ didn't take kindly to the disrespectful gesture and called out the fan, asking him if he'd like to apologize. After he apparently did not, Russ' crew member turns back and asks for some direction, to which Russ responds "do whatever you feel is right." The crew member then turns back around and pops the fan straight in the face, knocking him to the ground. 

Russ took to twitter afterwards to defend his actions and explain the situation. Watch a video of the punch, and Russ' explanation below.
