Real Housewives of New Jersey star Teresa Giudice began her 15-month sentence in a federal prison in Danbury, Conn. on Monday.

Giudice, who has appeared on the Bravo show since its premiere in 2009, turned herself in at around 3 a.m., her attorney James J. Leonard Jr. confirmed to ABC News.

“I think she was anxious to get in, get this thing started, get it behind her, and get back to her family. Her four girls are her primary focus,” Leonard said.

As for Giudice leaving prison early, her attorney said the decision falls in the hands of the judge and the bureau of prisons.

"Teresa is a very strong woman, she won't have any problems in there," he said in a statement to NJ Advance Media.

The 42-year-old will serve her time at the Federal Correctional Institution, which inspired the Netflix series Orange is the New Black. In prison, Giudice has the opportunity to take piano lessons, kitting classes and yoga. She may be transferred to West Virginia’s Alderson Prison Camp.

Giudice was sentenced in New Jersey in October for her involvement in a federal fraud case along with her husband of 15 years, Joe Giudice. Mr. Giudice received 41 months in prison and will start his sentence after his wife’s release. He also may be deported to Italy once his sentence is finished since he’s not a U.S. citizen.

After the couple was sentenced, they appeared on Watch What Happens Live where Mrs. Giudice revealed how their eldest daughter, Gia, 13, responded to the news.

"She was being strong for me I could tell. And she's like, 'Mommy don't worry about it. I'll be there. I'll help daddy with the girls. That will prepare me for when I'm a mom,’” she recalled her daughter saying about her three sisters, Gabriela, 10, Milania, 8, and Audriana, 5.

On Jan. 1, Gia shared a photo with her mother as they brought in 2015 along with the caption, “happy New Years with my best friend!!”
