Lisa Vanderpump's White Party Brings Bravo's Biggest Stars Together—Get the Details and See Pics From the Bash!

They may have to rename the Hamptons "Bravo Central" after Saturday's Bella New York magazine annual White Party, which drew so many network stars we almost thought we were at Andy Cohen's Bar Mitzvah.

The main attraction, of course, was current Bella New York cover woman and Real Housewives of Beverly Hills grande dame Lisa Vanderpump, who looked stunning dressed head-to-toe in Isabelle Armstrong. With husband Ken Todd by her side and dog Giggy in her arms, she looked right at home, despite being 3,000 miles away from her beloved Villa Rosa.

No wonder she was editor in chief Courtenay C. Hall's first pick for the cover.

Earlier in the evening, before Lisa hit the red carpet, former Real Housewives of New York City star Aviva Drescher and the cast of Secrets and Wives were among the first to arrive at Beautique, the chic Hamptons outpost where the party took place.

Aviva shared her thoughts with us on this season's RHONY drama: She's Team Luann and very much pro-Girl Code, in case you were wondering. Not long after, the Countess herself breezed in and let us know the video to "Girl Code (Don't Be So Uncool)" is getting ready to drop in a matter of weeks.

Her co-star, newcomer Dorinda Medley, was also in the house, along with boyfriend John Mahdessian. When asked about the upcoming RHONY reunion, both Dorinda and Luann hinted we'd see something "that has never happened on a reunion before," a sentiment Cohen echoed to us last week at Ramona Singer's book party. Watch what happens, we guess!

Shortly after Lisa made her entrance (after being privately flown in on ZIP Aviation, natch), three of her RHOBH co-stars—Kyle Richards, Lisa Rinna and Eileen Davidson—arrived at the bash, closely followed by a film crew. After mingling with their fellow Bravolebrities, the four women headed to a roped-off section by the pool where they filmed a scene while sipping drinks around a table.

We couldn't get close enough to overhear their conversation, but at one point, things looked serious in tone. Sadly, this comes as no surprise as later in the day E! News confirmed that Kyle's sister Kim Richards had been briefly hospitalized. On the red carpet, Vanderpump, Rinna and Davidson told E! News they wished Kim only the best.

While the RHOBH cast filmed, other guests milled about the party, sampling Calvisius Caviar and Lisa's LVP Sangria while scooping up hair products from Peter Coppola and adult toys from Lelo.

Fashionably late to the event was none other than Jill Zarin, accompanied by Glee star Jenna Ushkowitz and daughter Allyson Shapiro. Allyson, who recently buddied up with Gigi Hadid at a Hamptons nightclub, told us she just might consider a potential Children-of-Real-Housewives spinoff. Andy, are you listening?
