Real Housewives of New Jersey star TERESA GIUDICE is in danger of losing her children — because of her husband’s bad-boy behavior!

JOE GIUDICE’s violent outbursts and booze benders border on child neglect, says an expert, and now those close to the couple are terrified that a tragedy is bound to happen.

“I think Teresa and Joe will lose their kids if they don’t clean up their act,” a source told The ENQUIRER.

“She’s being called a horrible mom and in my opinion, Joe’s the big, bad, bullying dad. And unfortunately for them, the proof is all caught on tape.

“Not only does Joe show his true colors by appearing intoxicated and fighting during episodes, but it’s clear that their daughters – especially Gia – are suffering from his and Teresa’s poor parenting skills.”

During one booze-filled play session with Gia, Joe took a tumble and chipped his tooth on his marble floor. A terrified Gia sobbed at the sight of her dad’s bloody mouth.

“If Teresa had any brains at all, she wouldn’t leave her girls alone with Joe when he’s drinking,” said the source. “It’s an accident waiting to happen. Child Protection Services needs to watch a few episodes and they’d see for themselves that there’s enough evidence to use in a child neglect case.”

Teresa, 39, and Joe, 41, are the parents of four daughters – Gia, 10, Gabriella, 7, Milania, 5, and Audriana, 2.

In January, a New Jersey judge ordered Joe to pay $260,000 to former business partner Joe Mastropole for forging his ex-pal’s signature on a mortgage document. Two months later, he was arrested at the couple’s home and charged with fraudulently obtaining a driver’s license.

“This guy is certainly not a role model for the kids and appears to have a drinking problem,” Dr. Terry Lyles, a Florida-based psychologist and expert on stress and trauma, told The ENQUIRER.
