Never underestimate how dangerous it can be to be a squeaky-clean pop star. Bieber found himself in a situation not unlike that which killed Princess Diana back in 1997 as he sped down an L.A. freeway Friday. L.A. police received at least 10 911 calls about Bieber's chrome Fisker Karma ride swerving through traffic at speeds up to 100 miles per hour, but it was no joyride for the "Baby" singer. Bieber was being pursued by a super-aggressive paparazzo, and he was finally pulled over by police for reckless driving when they clocked the 18-year-old at 80 mph. Among the 911 callers was Dennis Zine, an L.A. city councilman and retired police officer, who told TMZ, "I didn't know it was Justin Bieber until later. He was going from the fast lane to the slow lane to the shoulder in traffic. It was a very dangerous driving situation. I figured someone was going to crash, so I called 911." Bieber has since filed a harassment complaint against the paparazzo, whose license plate he was able to report to police. When police stopped by Bieber's video shoot later Friday afternoon to take his statement, the paparazzo in question was there snapping pictures. He's officially under investigation, needless to say...
