The My Prerogative singer and his second wife, Alicia Etheridge, are already parents to son Cassius, born in 2010, and seven-month-old daughter Bohdi, and now multiple reports suggest the couple is preparing to welcome its third child.

Bobby, 47, is also a father to 29-year-old Landon, 25-year-old LaPrincia, and 23-year-old Bobby Jr., while his daughter with the late Whitney Houston, Bobbi Kristina Brown, died on 26 July (15), days after baby Bohdi was born.

Bobbi Kristina, 22, never regained consciousness from a medically-induced coma after she was found face down and unconscious in a bath tub at the Roswell, Georgia home she shared with her boyfriend Nick Gordon on 31 January, 2015.

A representative for the New Edition star, who wed Alicia in 2012, has yet to comment on the pregnancy reports.

He previously opened up about the loss of Bobbi Kristina, insisting he still feels close to his little girl, while crediting his large family with helping him deal with his grief.

"I've gained another angel to carry me through," he told America's WBLS radio host Deja Vu in October (15). "I'm really blessed with my children and everything that I have to do is about that. It's about love. I have a lot of love around me and have a lot of love that I give. It's about that."

Bobby also admitted writing his forthcoming memoir had proved to be extremely therapeutic.

"We've been working hard on it and I'm just trying to get all the cobwebs out and trying to be as honest as possible," he added. "My story is really deep, but it's funny and it's a whole bunch of things. You can find humour in it. I can, because I lived it. But you can also find some sad parts and some crazy parts."

Bobby is also hoping to adapt his memoirs for a movie.

The book, titled My Prerogative, is scheduled to hit retailers in June (16).
