Chris Brown's been sounding all contrite and abashed lately, but when you read the charges being filed today re his alleged assault of girlfriend Rihanna, his pleas sound just a wee bit hollow. And what's up with the ear-biting? Besides being way too Mike Tyson, it just sounds, well, awkward. He bit her ear? While he was driving? How's that work?

Here are the charges,courtesy HuffPo. He's scheduled to be arraigned at 330 p.m. afternoon.

According to a detective's affidavit, Brown and Rihanna got into a fight early Feb. 8 after the "Umbrella" singer checked her boyfriend's cell phone and found a text message from another woman.

Brown pulled his car over and tried to push Rihanna out, but she was still wearing her seatbelt, Los Angeles police Detective De Shon Andrews wrote. He said Brown pushed Rihanna's head against the window, punched her with his right hand, and then continued driving while hitting her, the affidavit states. He also bit his girlfriend on the ear, the affidavit states.

The affidavit was filed as part of a search warrant request for the phone records of Brown, Rihanna and her assistant.

Brown allegedly threatened to kill Rihanna after she pretended to leave a phone message with her assistant, telling her to have the police waiting at her house.
