Gorgas getting down! Real Housewives of New Jersey mainstay Melissa Gorga threw her husband Joe an intimate 40th birthday party in Atlantic City this past weekend.

An insider tells Us Weekly that the Bravo Housewife, 35, hosted the bash in a private room of Vic & Anthony's Steakhouse in the Golden Nugget. Seven other couples joined the lovey-dovey pair, including Melissa's sisters Lysa Simpson and Kim Pirrella. Noticeably absent? Their in-laws Teresa and Joe Giudice.

Melissa presented her husband with a three-tier casino-themed cake embellished with playing cards made of fondant. The parents of Antonia, Gino, and Joey were photographed nibbling on the sweet deck of cards to top off their meal.

After dinner, the group hit Haven nightclub, where they boogied on the dance floor and gambled inside the casino. "The two were holding hands all night and enjoying time with their family and friends," the source says.

In an interview with Us Weekly last November, Melissa said she and her husband enjoy hosting events. "Joe and I are big entertainers," she explained. "We love to have lots of people over and yes, we have ridiculous amounts of food everywhere!"
