Justin Bieber was pulled over for reckless driving in L.A. on Friday. According to observers (at least ten of whom called 911 to report him), the Biebs was weaving in and out of traffic and possibly going as fast as 100 miles per hour. (He admitted to doing 80.) The pop star did, however, have an excuse: He was being followed by an extra-aggressive photographer against whom he's since filed a harassment claim. A city councilman who witnessed the incident told the L.A. Times that it reminded him of "the Princess Diana situation," which indicates that everyone really needs to slow down out there.
