It's safe to say Jill Zarin still runs with a fabulous circle of people.

As the Real Housewives of New York City alumna celebrated another summer in the Hamptons, the reality star decided to host a party for all of her Bravo friends. Let's just say plenty of familiar faces showed up for a good cause this weekend.

The O.G. of the O.C. Vicki Gunvalson represented the West Coast while Cynthia Bailey made the trip from Atlanta. Kathy Wakile from New Jersey arrived for a quick weekend stay.

As for Big Apple fans, you certainly had a handful of cast members in town. Kelly Bensimon, Kristen Taekman, Cindy Barshop and Ramona Singer came together to attend Jill's charity event benefiting St. Jude Children's Hospital.

"Love my Bobby and my REAL girlfriends," the hostess wrote on Instagram with a group photo. "Love you and thank you all for coming to my #jillzarinluxlunch."

During the afternoon, the Bravolebrities got to enjoy a wide variety of products including Cynthia Bailey Eyewear. And of course there was plenty of girl chat away from the cameras. Oh, to be a fly on the wall at this party.

"Great spending time with her," Vicki wrote on Instagram while posing next to Ramona. "She looks fabulous and happy."

In a separate post, Jill added that "this is the beginning of a REAL friendship ladies! #thank you for all your support this weekend."
