Federal prosecutors want hours of unaired footage of TERESA & JOE GIUDICE in their bombshell fraud trial.

After entering a not-guilty plea on fraud charges in Newark, Teresa,  greeted camera crews and fans who at the Porsche Boutique in Wayne, N.J. with apparently not a care in the world.

Meanwhile, prosecutors have asked Bravo to hand over hours of unaired footage from “The Real Housewives of New Jersey,” a network insider told the NY Daily News.

“For every hour that airs, there are more than 20 hours of unedited footage,” the source said.

“They shoot for three months and end up using only the footage that fits into the story line they want to focus on.”

Feds have charged the Giudices with of 39 counts of fraud, including conspiracy to commit mail and wire fraud, bank fraud, making false statements on loan applications and bankruptcy fraud.

The un-edited and un-aired footage has been requested to see if there’s a few “smoking guns” caught on tape that’ll help nail the Giudices.

“The network is not happy,” the source told the NY tab. “Everyone is asking if ‘Housewives’ ruined Teresa. The real question is, will Teresa ruin ‘Housewives’?”

If Bravo declines to hand over the footage, they’ll simply be subpoenaed to do so.
