They've been enemies for some time, and Real Housewives of New Jersey star Teresa Giudice won't be getting any sympathy from her co-star, Kim Granatell.

Joe & Teresa Giudice Sentenced On Fraud Charges

After Giudice and her husband were sentenced for fraud charges October 2, Granatell took to her Twitter page to slam the reality star-who received 15 months in prison-in a series of tweets.

Giudice's Crisis Manager Says 'Outcome Was Not Expected' In Fraud Case

This isn't the first time that Granatell has slammed her co-star, telling Radar Online in March that she was disgusted by her.

In March, Giudice did a cash-only book signing and donated the proceeds to charity, a move Granatell slammed as an attempt to improve her image in the public eye after she pleaded guilty to 41 counts of fraud.

"It's disgusting," Granatell exclusively told Radar Online. "Why hasn't she been donating all along?"

"We're going to try to reverse that role [of being the convicted felon] because we're facing jail time, so let's do anything that we can to show that 'I am a good person all of a sudden,'" Granatell added about Giudice's reasoning. "If I was facing jail time and I was her, I'd be cleaning streets and doing anything for the town."

Giudice was sentenced to 15 months while her husband, Joe, received a sentence of 41 months after they pleaded guilty to bankruptcy fraud, conspiracy to commit mail fraud and wire fraud, and failing to pay taxes from 2004-2008. Joe was also ordered to pay restitution to the tune of $414,588.
