It might make for fun viewing on The Real Housewives Of New Jersey, but Teresa Giudice's sniping is earning her a new breed of enemy in jail.

According to InTouch Magazine which claims to have spoken to a prison insider where the reality star is incarcerated, Teresa has made a target of herself by acting like she is above the other inmates.

'She thinks she's better than everyone else. She acts like the other women are beneath her, and she's making enemies because of it,' the source said. 'She told officials that she was afraid for her life. Once you start complaining about certain prisoners, you become a target. It would be wise of her to stop acting like shes above everything.'

Target: According to InTouch magazine Teresa Giudice has made herself a target by acting above her fellow prison inmates

Insiders claim the 42-year-old is writing a diary of her prison experiences with the intention of landing a seven-figure book deal after she serves her 15-month sentence for fraud.

'She's documenting everything for her book: who's sleeping with whom, who's been caught having sex, even little things like who's arguing over the flatiron. She's in a lot of debt and see's it as her opportunity to make a lot of money when she's released from prison,' the insider said.

'She uses the pink one as her diary and writes in it every night. All the other inmates want to know who and what she's writing about.

Bitching: The 42-year-old apparently complains about other inmates, the horrible food and having to clean up other people's bathroom messes, as she serves he sentence in the prison that is the real life setting for Orange Is The New Black

'Teresa complains all the time that the food is horrible. She also writes about how she has to clean up people's messes in the bathroom.'

One prison insider claims that should the pink notepad fall into the wrong hands behind bars, it could spell a lot of trouble for the mother-of-four.

'She'd be lost without it. She guards it with her life. When she's finished writing she locks it away - she's afraid someone will take it. That would be the end of her if someone read it and shared it with everyone else. She already has a target on her back. If that diary falls into the wrong hands, it wont be pretty.'

And apparently it's not just her fellow inmates the cookbook author is bitching about: 'Teresa yearns to be on TV again and writes about it a lot. She's writing about all the dirt and secrets, stuff no-one knows about. If she turns the diary into a book, her co-stars should be very afraid,' the source added.

Infidelity: According to sources, Teresa is convinced her husband Joe is cheating on her while she is behind bars, and she is planning on divorcing him

Another person on Teresa's chopping block is husband Joe; According to reports Giudice has already decided she is going to become a Real House ex-Wife

'She's done. She could even serve him with divorce papers [from] behind bars,' the article quotes. 'She's angry at Joe for doing this to their family, especially when she stood by him. Now she's in prison while he's out there living his life.

And Teresa apparently makes now secret of what she defines as 'living his life'.

'She was able to keep an eye on him when she was at home for the most part. But every night she's in prison she worries he's with another woman. And she's putting her thoughts to paper. She's convinced he's cheating,' the source said.
