Justin Bieber faces new reckless driving allegations, reports say Justin Bieber may have trouble keeping his foot off the accelerator. The 19-year-old pop star has once again been accused of driving recklessly inside his gated Southern California community, police say. The Los Angeles County Sherriff's Department confirmed to TMZ that police visited Bieber's Calbasas, Calif., house Monday night after receiving multiple phone calls from neighbors concerned about how fast the pop star was driving. Children were said to be playing nearby when Bieber was seen allegedly speeding through the area in his Ferrari. The calls to 911 reportedly came from two separate locations within the quiet residential neighborhood. Sources have told E! News the one of the concerned callers who spoke to police was former NFL wide receiver Keyshawn Johnson. This hasn't been Bieber's only recent speeding troubles. The 19-year-old performer was previously accused in March of driving recklessly near his home. Bieber allegedly spit on and threatened to kill one of his neighbors who confronted him at the time, according to reports. Local prosecutors are currently reviewing that case. Bieber has yet to comment on this most recent incident.
