Teresa Giudice has not allowed sister-in-law Melissa Gorga to visit her while she serves out her 15-month sentence on bank fraud related charges at the Danbury Correctional facility.

RadarOnline reports, despite Giudice being locked away for the last eight months, the feud between the two "Real Housewives of New Jersey" stars remains as bitter and intense as ever it's ever been.

"Teresa refuses to allow her to come see her in a prison," said a source. "Melissa said, 'I have asked to go see Teresa, but Teresa refuses to see me. She just refuses."

The two don't figure to be able to avoid one another for much longer, as Giudice has already signed on to rejoin the "Real Housewives" cast once she is released from custody sometime around Christmas time.

"The only reason Teresa will see them is because she needs to film with them and they all really need the money," a source added. "Bravo is going to start filming when Teresa gets out. Everything is waiting on Teresa. There aren't any contracts yet, no filming yet."

Word is the plan will figure out how to get the families communicating over the upcoming holiday season and take things from there.

Once Teresa has been released, husband Joe is slated to commence serving out the terms of his 41-month sentence on similar charges. Whenever he is released, Joe also faces the possibility of being deported back to his native Italy.

He recently starred in the network spin-off "Real Housewives of New Jersey: Teresa Checks In," chronicling his life as a single parent to his four young daughters while his wife is away.

Teresa also starred in the series via jailhouse phone calls with family members and has also already signed on to pen a prison tell-all about her time behind bars.
