Even getting her hair and nails done behind bars. We were there last weekend, she made us wait an hour to do her hair. I mean, really? Reporter: Guidice saying his wife of 16 years works out three times a day, goes to church, has a crew of women she hangs out with.

Reporter: Teresa Guidice spoke with "Us weekly" about her jailhouse routine. She makes up about 6:00 A.M., puts her khaki-colored trouser suit on. She does her first workout of the day. Then she goes to get breakfast in the prison kitchen which usually is oatmeal and eggs. Her husband is raising their four daughters and says the family tries to visit their mother every weekend in the federal correctional institute in Danbury, Connecticut. The very prison that prompted the netflix hit series "Orange is the new black." By no means is it like the TV show at all. I mean, these women are doing their hair and nails. She's working out three times a day. The food is not terrible from what she says. Reporter: Despite her time in press soon, Guidice is said to be keeping well. Her 14-year-old daughter Gia spoke about visiting her mom. She looks so good. Like it's nothing like anyone would expect. Like she just looks so amazing. I'm the queen.

You know, pretty much sets my schedule. You know. So that is awesome. She's arranging play dates from behind bars, making sure the girls turn in their projects on time. She's booking appointments for when she gets out. She's staying on top of everything. Reporter: Before Teresa's legal drama was playing out in court -- Be a man, stick with your blood! Reporter: It was playing out on reality TV. Like Teresa's temper she and Joe seemed to have it all. The happy family. And a huge mansion. My house is pretty much all marble, granite, onyx. Reporter: But that American dream came crashing down when Teresa and Joe were each charged with 39 counts of fraud. She spoke with ABC's Amy robach about the effect of the case on her four daughters. What's the hardest part? My kids going through this every day. It's a lot of pressure when you're trying to make your kids feel safe, when you're uncertain. How do you do it? I'm a role model for them. I can't be upset and curl up in a ball and go in a room and lock the door. When the door is shut and they are in bed, do you get to do that? Yes. And I do do that. I'd be lying to say I didn't. We're in a different place right now. Reporter: Teresa was cheery-eyed on her last "Real housewives" episodes. I'm trying. Reporter: She said on bravo's "Watch what happens live" that she was ready for her punishment. I made my mistake, I'm paying for it. After that I'm just going to get right back up and keep going.
