Justin Bieber isn't just a little punk, he's also got a lead foot. The pop star has gotten himself in trouble numerous times for speeding, but this time he's pissed off the wrong guy: former Super Bowl-winning NFL wide receiver Keyshawn Johnson. Apparently the two live in the same Southern California neighborhood, and when the 6'4" athlete saw 5'7" Bieber speeding down his street in his Ferrari 458 Italia at nearly 100 mph while the Johnson family was enjoying a BBQ on the lawn, Johnson chased him down in his Prius, busted through his security and had some words.
