Police sources tell TMZ that they responded to the scene after receiving a frantic call from Perri. The singer reportedly had been waiting to pull into a building during the wee hours of the morning, when a male approached her car and attempted to open the driver's side door.
As the gossip site reports, "The man instructed her to 'move over' and tried to shove himself into the car -- but she wouldn't budge ... and a struggle ensued."
So how exactly did the brave songstress fight off the thug? Besides physically defending herself, Perri also honked her car's horn in an attempt to draw attention to her attack.
Thankfully Christina was able to ward off her would-be carjacker, but did not get off totally unscathed. According to reports, Perri was struck on the head and numerous places on her body during the attack.
Police have not identified a suspect as of yet. We'll continue to update as this story develops.
