New Jersey Housewife Teresa Giudice has been at war with former castmate Caroline Manzo for years, but the pair reportedly cleared the air with each other ahead of filming a commercial together last week.

“Teresa came to LA for about 24 hours to film something with Caroline Manzo,” a HollywoodLife source told them.

“They filmed a commercial together and hadn’t seen one another in years. They were both professionals, but of course, it was a little awkward at first.”

The source continued, “They spoke on the phone before they saw one another where they said what they needed to say to move on,” the insider continued. “This really helped clear the air for them to see one another, and it was peaceful and respectful with zero issues.”

The news is surprising considering just weeks ago, Teresa alluded to the fact that she believes that it was Caroline who turned her and her soon-to-be-ex-husband, Joe Giudice into the feds.
