Paparazzi chasing Brit Brit were busted late last night in Los Angeles. Around 11:20 PM last night, according to law enforcement sources, police pulled over a total of eight vehicles driven by photogs, after they were observed driving evasively at a high rate of speed and making dangerous lane changes in and around Mission Hills. Four of the drivers were arrested.
We're also told that Britney herself told cops that one of the cars may have tried to "run her off the road," but she couldn't ID which car it was, so no action was taken
