At 12:05 PM PDT, Chris Brown arrived at his attorney Mark Geragos‘ downtown Los Angeles office, RadarOnline.com has confirmed. The office is within walking distance to the courthouse where the preliminary hearing in the felony assault case against Brown will begin at 1:45 PM. But don’t expect the two men to hoof it over to the Superior Court Building. They’ll be jumping into their chauffeur-driven SUV for the ride over in about an hour. Rihanna, the victim and prime witness in the case, is expected to arrive just as the doors close at 1:45.
