The couple, who have been dating for almost a year, are said to have come to blows after an argument inside a vehicle. "She got out of the car to walk home," a source told the New York Daily News. "He got out to stop her, things got physical. He hit her, possibly more than once. She had multiple bruises." 

Rihanna reportedly dialed 911 and by the time officers arrived, Brown was gone. A security guard at Cedars-Sinai Medical Center in Los Angeles told the Daily News on Sunday night that he saw Rihanna being taken for treatment at the hospital. Last night Chris left the police station after being released on $50,000 bail. He is reportedly due in court on March 5th.
