Last night's Grammy Award Ceremony in L.A. was overshadowed by the absence of Chris Brown and girlfriend, Rihanna, who pulled out just hours before the show was due to start, with Al Green, Justin Timberlake and Boys II Men brought in to fill Rihanna's slot on this short notice.

The 19 year old R'n'B star was arrested regarding a "domestic violence felony battery" allegation after an unidentified woman accused Brown of assaulting her in a car in Hancock Park, L.A., shortly after leaving a pre-Grammy party.  The woman in question suffered visible injuries and identified Brown as her attacker.

Brown turned himself over to the L.A. police and is currently on bail of €50,000 and will appear in court to face the charges on March 5th. There has been speculation that the injured woman may be Rihanna herself, but her spokesperson has claim that Rihanna was caught up in an unspecified traffic problem. Hmmm... convincing
