With Bravo set to unveil our very first scripted series on December 2, we did what we do best to celebrate: we threw a party!

The stars of the the show—Lisa Edelstein (above), Necar Zadegan, Alanna Ubach, Julianna Guill, and Beau Garrett, along with executive producer Marti Noxon—toasted the premiere with an exclusive bash at L.A.'s Theatre at the ACE Hotel Tuesday night. And they were joined by many of their new Bravoleb family members: Real Housewives' stars Brandi Glanville, Tamra Judge, Shannon Beador, Lisa Rinna, Eileen Davidson, plus Flipping Out's Jeff Lewis and Jenni Pulos. Also in the house: GG2D's male stars Paul Adelstein, Warren Christie, Matthew Glave, Brandon Jay McLaren, Michael Weaver, and J. August Richards.

Before entering the bash to sip on cocktails and snack on Bravo-branded chocolate and vanilla cupcakes, the stars and guests posed for pics—and shared some behind-the-scenes gossip from filming. "I have worked with some of the best crews around, but this particular group is a truly unique one," Lisa Edelstein told the Dish a few days before the bash. "They frequently burst into song! Song! With harmonies! Mostly it's 'Happy Birthday' (regardless of if it is their birthday or not) and mostly it's if someone does something awesome or awesomely embarrassing. Applause, too, they are big on applauding. It is just a fantastic collection of beautiful weirdos that have great leadership and a great work ethic."

We also asked Richards (who plays Ford on the show) to describe the series in three words: "Romantic, tragic, and fabulous," he said, adding that he's a bit nervous about certain upcoming episodes: "In one, I had to give a really big speech at the Family Equality Gala and it was a lot of dialogue and I hope I did OK!" (We're sure he did!)

Necar Zadegan, meanwhile, is nothing but confident when it comes to her more revealing scenes: "I'm proud of everything!" she said. "I have a really wonderful actor, Matt Glave, who plays my love interest. We did some great scenes together. If we didn't have such fun working, I might feel [nervous], but we had a great time!"

RHOC's Shannon Beador, who attended with her husband David, is already a big fan of GG2D: "I am so excited to see the show!" she gushed. Though the series chronicles a woman trying to pick up the pieces of her life after her marriage falls apart, Shannon, who's been happily wed for years, doesn't totally relate to Lisa's character: "Divorce isn't an option," she said. Still, she admitted, "I've seen quite a few of the different trailers and it looks hilarious!"
