Chris Brown CBrownDrivArc1.jpg OMG! This just keeps getting worse...

Radar Online reports that blood was found by police inside of the rented silver Lamborghini Chris was driving the night that Rihanna ended up in the hospital.

Police impounded the vehicle after the February 8 incident between the couple, and they say the blood was visible between the front seats and the car's interior, and it shows "many signs of a violent struggle."

After hearing this and seeing those pics of Rihanna's battered face, it's pretty hard to believe that there still isn't enough evidence to charge Chris with SOMETHING that results in jail time!
