Joe Giudice, husband of the Real Housewives of New Jersey's Teresa Giudice, discussed family life and how her wife deals with life inside prison. 

Joe has admitted that raising their four children alone has been extremely difficult, when Teresa left on January 5 to start her prison sentence for the fraud charges.

In a new interview with Extra, which will air Wednesday, he said that he has to stay strong for their kids and acknowledged how Teresa's being away and everything that she did made him appreciate her a lot more.

And if any of you Real Housewives of New Jersey fans are worried about how prison might change Teresa, worry not, as Joe just confirmed that despite being in prison, she remains faithful to her beauty regimen.

Speaking up about a time they visited her in prison, Joe said that Teresa made them wait for an hour because she had to do her hair. "That was a little annoying," he said.

Joe added that Teresa now has new friends behind bars-a close, little group that she always hangs out with, goes to the gym with and does her regimen with every single day, including doing her hair and her nails.

Joe shared that he, as well as their daughters 13- year old Gia, 9-year old Milania, 8-year old Gabriella and 3-year old Audriana try their best to visit Teresa every weekend and that their mom is constantly in contact with them.

Teresa was originally given a 15-month prison sentence, however People magazine reported last January that, the sentence might be reduced and she might be able to get out of jail sooner. After Teresa is released, Joe will begin his 41-month prison sentence.
