Bobby, 46, was accompanied by his wife Alicia Etheredge and his daughter LaPrincia Brown, 24, as he arrived at the hospital early Wednesday morning, wearing a baseball cap and thick snow jacket, reported Us magazine.
The anguished father kept his eyes down and focused on his cell phone, choosing not to answer any questions put to him by gathered reporters.
The 21-year-old aspiring singer was moved to Emory University Hospital earlier this week after initially being hospitalised at North Fulton Hospital in Roswell.
