Teresa Giudice is hoping to be pregnant with her fifth child before husband Joe has to commence serving his 41-month federal prison sentence.

Radar Online reports the recently freed 43-year-old "Real Housewives of New Jersey" star and her husband have already started working on trying to conceive.

"They are definitely trying to have a baby," said a source. "She and Joe have been intimate since she got out of prison in December. She really seems to be glowing right now. She looks like she could be pregnant already."

Teresa's Former Cellmate Speaks out

Word is Teresa frequently talked about having another child while she was serving her 15-month sentence on fraud related charges at the Danbury Correctional Facility.

"She talked about it when we would all pass around baby photos," said former cellmate Deseree Bradshaw,

Speculation is part of her motivation could be maintaining her place in the world of reality TV.

"Teresa knows a baby would be ratings gold, especially with her as a single mother with Joe in jail," a source added. "And it would be a dream for Bravo, too. Everybody wins."

In addition, talk is a new baby could perhaps help Joe's cause once he's finally released from prison if authorities decide to seek to deport him back to his native Italy.

"He believes that if Teresa has a baby, there's a better chance she would follow him to Italy."

Giudice Pushing new Memoir

Meantime, Teresa is hard at work promoting her new prison memoir entitled "Turning the Tables: From Housewife to Inmate and Back Again."

North Jersey News reports she recently turned out for a book signing in nearby Ridgewood that was flooded by adoring fans snapping cellphone photos of her.

Giudice's house arrest was recently lifted. And since then, she's been spotted all over town at various media events. Of her fans, she recently marveled they "never turned their backs on me and have been with me on this crazy journey."
