The Real Housewives of New Jersey drama between Margaret Josephs and Jennifer Aydin continues.

In the exclusive sneak peek below, the ladies of the Garden State are in Cabo and gift Teresa Giudice a necklace her fitness competition. But the necklace seems to be the issue. Jennifer's brother is a jeweler.

"Would've come out better if my brother did it," she says.

And that's what sets off Margaret.

"Jennifer, I don't know what the hell you're talking about because I called you and told you and you were like, ‘Fine.' I think the cocktails are getting to your brain," Margaret says.
