"Real Housewives of New Jersey" star Teresa Giudice is supposed to begin her 15-month prison sentence on Jan. 5 after being found guilty of bankruptcy fraud. The Bravo star, along with her husband Joe Giudice, was sentenced in October.

Reportedly, Teresa is panicking about going to prison and hasn't told her youngest daughters why she's going away. A source told Radar Online that the 42-year-old told Gia, 13, and Gabriella, 10, that she's going to jail but 8-year-old Milania and 5-year-old Audriana don't know the truth.

"Teresa and Joe feel that they are too young to fully comprehend what is going on," the source told Radar. "Teresa and Joe are telling the girls that she is going away to work."

Another source told the site that Giudice isn't pretending she'll be filming but told the little girls that she's working "on a book about jail." According to Hollywood Life, Giudice asked three of her "RHONJ" costars to help look after her daughters while she's away.

A source said she asked her sister-in-law Melissa Gorga, her cousin Kathy Wakile and her best friend Dina Manzo for help.

"Teresa is terrified of going to prison. She has put Gia in charge of looking over the girls," the source said. "She does not trust Joe at all, he can't even do their hair! Teresa cries all day, all night. She is sick over leaving them."

"Melissa, Kathy and Dina are all going to be taking shifts coming over and watching them, picking them up from school and taking them on the weekends," the source added.
