Chris Brown has taken to Twitter.com to defend himself against fresh accusations he left the scene of a traffic accident without exchanging details with the other motorist. The embattled R&B star has been charged with hit-and-run relating to the minor car accident in Los Angeles last month (May13), despite claims from Brown's representative and lawyer Mark Geragos that he did what he was required to do at the scene - and even contacted the female motorist he ran into to make sure she had the correct details. He has also been charged with driving without a valid licence, and faces up to six months behind bars for each offence. But angry Brown insists he's completely innocent and in a series of tweets on Tuesday (25Jun13), he attempted to clear his name. He wrote: "It's not a hit and run if u (sic) get out the car, exchange information (who has NO DAMAGE to either cars).This is really ridiculous... I have a valid drivers license and I gave the woman the right info. She saw cameras and wanted to make a scene. "She contacted the cops thinking of a payday from Chris Brown when I followed the proper procedures... My lawyers will be contacting you. I will not stand for this bullying and yellow journalism!" Brown also changed his Twitter profile picture to a photo of him chatting to the other motorist at the scene of the accident, adding, "My profile pic is the pic I took of the persons (sic) car after 'the hit and run'. NO damage. Just a dirty car.once again, I gotta clear my name." He then attached a photo of the rear of the Mercedes he ran into in a bid to prove the car was not damaged.
