In his first public appearance since the plane crash that injured him and Travis Barker, Adam "DJ AM" Goldstein attended a memorial service yesterday for his friend Chris "Lil' Chris" Baker, who was one of four people who didn't survive the September 19 crash. Adam arrived in a limo to the Forest Lawn Memorial-Parks & Mortuaries in Hollywood and was visibly scarred. He left Doctors Hospital in Augusta, Ga., last Friday via airplane. Travis Barker, meanwhile, left the hospital on Monday and is returning to California on a bus.
