Teresa Giudice is Behind Bars

The 'Real Housewives of New Jersey' star is now in federal prison.

Teresa Giudice turned herself into authorities shortly after 3am this morning to serve a 15-month prison sentence for fraud.

According to People Magazine,

"Being away from her four young daughters, Gia, Gabriela, 10, Milania, 8, and Audriana, 5, is the most difficult part of all of this for Giudice."

When she's done serving her time, her husband Joe will serve a 41-month sentence.  Also, because Joe is not a U.S. citizen, he may be deported after his sentence.
