Teresa Giudice breaks silence on her jail sentence for fraud charges. The reality star opened up about the legal problem in an interview with "Watch What Happens Live" airing on Monday, October 6. Speaking to host Andy Cohen, an emotional Teresa also talked about her daughter Gia who promised that she would help take care of her siblings when she is in prison.

"I was so nervous. ... At one point, I couldn't even move my fingers," she said of the October 2 court session. "They were stuck. I couldn't open my hands ... my nerves were shot, I've had sleepless nights. I was shocked. It was very unexpected. I don't even know what to say."

In the interview, Teresa also shared that her 13-year-old daughter Gia provided much support for her during the difficult time. "She was being strong for me, I could tell. She was like 'Mommy, don't worry, I'll be there. I'll help Daddy with the girls; that'll prepare me for when I'm a mom.' That broke my heart when she said that," she said.

Teresa is going to start her 15-month term on January 5. Her husband Joe Giudice who received 41-month sentence would serve later so that one of them could be at home for their kids. Calling Joe a "great father, a great husband," Teresa revealed, "All I said to my husband was, 'All you have to do is take care of our daughters. That's all I ask.' "
