The musician was charged with assaulting and making criminal threats against his girlfriend, R&B singer Rihanna, who's given name is Robyn Fenty. Brown was released on $50,000 bail. The case will be presented to the Los Angeles County District Attorney's office, where additional charges are possible.

TMZ is reporting that a police source likened Rihanna's injuries to what you would expect on an MMA fighter. The injuries are described as two huge contusions, with significant swelling and bruising, on either side of her forehead. The singer received a bloody lip and nose as well as bit marks on her arms and fingers.

The couple had attended the Clive Davis Pre-Grammy party in Beverly Hills on Saturday evening. According to the Los Angeles Times, the couple left the event and got into a verbal and physical altercation while Brown was driving in the Hancock Park neighborhood. He stopped the car and Rihanna reportedly got out and called for help on her cellphone.

Rihanna's 911 call brought law enforcement officers to the scene, where they aided the 20 year old singer and discovered that Brown had fled. According to the NY Daily News, Rihanna was treated at Cedar-Sinai Medical Center for her injuries.

Both singers canceled two hours before their scheduled performances at the Grammys. Rihanna had planned to sing Disturbia and Brown was slated to sing Forever. Show producers scrambled for additional performers, securing Justin Timberlake as a last minute replacement. Check out winners and red carpet photos here.
