Rihanna bruised, Chris Brown under investigation for domestic violence

Rihanna has canceled her Grammy performance tonight, after what sources are claiming is a car accident that left her face bruised.

At the same time, Rihanna’s boyfriend Chris Brown is being investigated by the LAPD after an alleged assault on an “unidentified female.”

According to ET, police say Brown and the woman were in a vehicle in the Hancock Park area of Los Angeles when, following an argument, the woman was allegedly injured, naming Brown as her attacker. When police arrived, they only found the woman; Brown had left.

Coincidence?
