Teresa Giudice and her sister-in-law Melissa Gorga, costars on the reality show The Real Housewives of New Jersey, acted friendly toward each other at an event on Feb. 18, which sparked rumors that they put their long-time family feud behind them. 

The two women and their husbands both named Joe, who also reportedly disliked each other, smiled and posed together for photos at the launch party of Teresa's Milania Hair Care held in New Jersey.

During the season four reunion special of their Bravo show, which aired in October of 2012, the Gorgas and the Giudices screamed at each other over allegations that Teresa planned to "embarrass" Melissa at a fashion show by inviting a man who claimed the mother-of-three was once a stripper at his nightclub.

At the event on Monday, however, an eyewitness told InTouch "It seemed like they had reconciled and put the past behind them," adding, "there was a lot of laughing and joking around between the families."

The magazine also noted that the Joes messed around in a friendly way with each other at the party. Teresa "ran over" to the Melissa and her husband as soon as they arrived at the event and "kisses were exchanged," according to The Record newspaper. The husbands then welcomed each other with hugs and kisses before posing for photos together. 

The most recent spat between Teresa and Melissa took place in January when they got into a fight at a birthday party for Teresa's 12-year-old daughter Gia. An eyewitness told the magazine, "Melissa got [verbally] attacked by Teresa and her friends."

Teresa's friend Kim D. "was drunk and was the instigator, stirring the pot - as always - over petty stuff," the eyewitness added.
