Bieber's Driving Prompted 10 Calls to 911 LA councilman Dennis Zine calls 100mph estimate 'conservative' By Neal Colgrass, Newser Staff Posted Jul 7, 2012 5:50 PM CDT 26 comments Comments Canadian singer Justin Bieber performs at a German paper Bildzeitung 's headquarters in Berlin, Friday, June 8, 2012. (AP Photo/dapd/ Timur Emek) (Newser) – Looks like LA councilman Dennis Zine wasn't the only one worried about the Biebs' driving yesterday. Turns out 9 other drivers called 911 to complain about Justin Bieber's reckless ways on the Hollywood Freeway before CHP officers pulled him over, TMZ reports. The singer insists he was only doing 80mph, but Zine says it looked like 100mph—and he calls that estimate "conservative." TMZ says paparazzi drivers were hunting Bieber, and Zine acknowledges that celebrity life is no picnic—but "any time you do 90, the paparazzi are going to go 90," he tells the LA Times. Another little tidbit: A source tells TMZ that a member of Bieber's security team was in the car and allowed the 18-year-old to gun it on a busy freeway.
