Joe Giudice's off-center behavior has become so erratic his four young daughters now fear him, and he often leaves them in tears by constantly screaming at them.

With "Real Housewife of New Jersey" wife Teresa Giudice still away incarcerated serving out the remainder of her 15-month sentence on fraud related charges, Radar Online reports Joe regularly "yells and curses at his daughters."

One recent occasion Joe suffered a meltdown in front of his in-laws, leading them to confront him about his behavior.

"Audriana, the youngest, was in the bathtub and the water overflowed and came through the light fixtures in the kitchen," said a source. "Teresa's mother and father were there and Joe noticed the water and started swearing and cursing like a crazy person."

The source later added, "He went flying up the stairs yelling, 'Why isn't Audriana monitored?' He was cursing out Gia and he yelled at Audriana as well."

Witnessing the girls in tears, Teresa's mom reportedly sought to remind Joe that they were only children, and her father screamed at him that he had never acted in such a way with any of his children.

Earlier this month, police were called to the family's Jersey Shore home after a neighbor overheard him berating teen daughter Gia after she accidentally locked herself out of the house.

On top of all that, sources claim far too often Joe leaves the girls alone to fend for themselves while he's away socializing. Reports are he has become a regular at the nearby Rails Steak House where he is often seen "with his other woman."

"It's not enough supervision for four little girls," said a source. "When you have four girls, they are always going to be getting into mischief -- and he doesn't seem to care or pay any attention to them."

Some attribute Joe's increasingly neglectful behavior with him having to deal with the knowledge that he is slated to commence serving his own 41-month prison term on similar charges as soon as his wife is released.

"Joe knows he's going to jail in a couple of months, so his miseries are more important to him than his daughters," a source added.
