Bobby Brown, wife expecting baby

Emotions are running high for Bobby Brown.

When stopped outside Emory University Hospital on Thursday by Access Hollywood, he briefly said that daughter Bobbi Kristina is doing "good," adding, "We're praying."

As he continues his bedside vigil for his only daughter with Whitney Houston, he also has shared the news with family members that his wife, Alicia Etheredge, 41, is four months pregnant, according to multiple reports.

It will be Bobby's sixth child.

Bobby, 46, and Whitney Houston divorced in 2007.

He married TV producer Alicia in 2012. In June 2009, Bobby welcomed his fifth child, Cassius Brown, with Alicia.

He has three children with his ex-girlfriend Kim Ward – Landon, 26, LaPrincia, 25, andBobby Jr., 21.

Members of Houston's family and the Brown family have been gathered around Bobbi Kristina's bed at Emory University Hospital, where she is on a ventilator after being found unconscious in her bathtub on Saturday.

Tensions have been said to be high between the families. And although a source close to the family tells us that's not true, a fight did break out between two family members early Friday morning.

Gannett TV station, WXIA-TV, is reporting that Tina Brown, Bobby Brown's sister, hit Shayne Brown, a cousin of Bobby Brown, in the head with a bottle. Police were called, but Tina left before they arrived. Shayne drove himself to a nearby hospital.
