Who's Joe Giudice talking to?
The husband of Real Housewives of New Jersey
star Teresa Giudice
has been caught on camera using some highly offensive language while speaking about his wife.
While the New Jersey
cast, including the Manzos, the Lauritas, the Wakiles and the Gorgas, are all in Napa, Calif., to celebrate Caroline Manzo
's 50th birthday, Joe excuses himself to take a phone call – for work, he says. (Watch a clip of the footage below.)
What he says on the phone at first – in English – to the person on the other end isn't necessarily incriminating. But once he sees his wife walking over to him, the name-calling begins.
"Here she comes, my b–– wife. She's such a c––," he says. "I'm going to hang up."
When Teresa asks, "Who are you talking to?" he replies, "A worker, what the f––?"
He also calls Teresa – to her face – a "pain in the ass" and a "re––."
Then he tells Teresa that the "worker" on the phone doesn't understand English. He then starts to speak in Italian, seemingly to back up his claim about who is on the phone.
A source tells PEOPLE about the couple, "She and Joe are still together, and Teresa says they're fine."
The episode of The Real Housewives of New Jersey
airs Aug. 19.
