Joe Giudice -- Cops Called After Fight With Neighbor

Police were called to Joe Giudice's beach house in New Jersey on Saturday after an argument with a neighbor got out of control.

A witness tells TMZ Joe's oldest daughter Gia was locked out of the house and trying to get in for several minutes. Once Joe finally let her inside, he could be heard screaming at Gia from the backyard ... that's when a neighbor stepped in.

We're told the woman approached Joe's house and the two got into a shouting match. The neighbor could be heard yelling, "this guy is crazy, he's dangerous, call the cops."

Officers arrived to diffuse the situation and we're told Joe's daughters were begging them not to arrest their father.

A law enforcement source says no arrests were made and the argument was settled peacefully.

A rep for Joe says the whole thing started because Joe was having a party and the neighbor felt it was inappropriate for children to be around.
