Keyshawn Johnson is currently in a feud (of sorts) with pop icon Justin Bieber. (Nope, you read that right) The former NFL star and football commentator is claiming that the pop star is "playing with dynamite" by endangering Keyshawn's family with his reckless driving. 

Sources spoke with Keyshawn's agent Jerome Stanley about the recent incident. Stanley reports that "...Keyshawn is "very, very, very livid" with Justin for blazing through their Calabasas community in his Ferrari on Monday." The issue only gets more complicated when you realize that Keyshawn was currently walking with his children. 

As previously reported, Keyshawn jumped in his Prius and tried to chase Bieber down, undoubtably to give him an earful. Maybe more. He supposedly tried to confront Justin Bieber, but the pop singer fled the scene to the inside of his home to avoid conflict. Now, I know what you're thinking. Keyshawn doesn't look like a "Prius guy." I thought the same thing.

"Keyshawn is taking the situation very seriously," Stanley says ... "He wants Justin to slow down and be a responsible neighbor."

California police have received multiple phone calls from concerned neighbors reporting Bieber's dangerous driving. As of now, the L.A. County Sheriff's Dept. has launched an investigation into the matter. When asked if Keyshawn plans to aid in the investigation, Stanley replied, "Keyshawn is a law-abiding citizen and he'll do whatever it takes to help the authorities."
