Camille Grammer and Kyle Richards Party Together. Seriously.

Hell might want to stock up on snow shovels: Kyle Richards and Camille Grammer seem to have put their dinner party drama behind them. Can we get a Vicki Gunvalson-sized "Woo hoo"?

HollywoodLife.com reports that the girls "were hanging out together all night — drinking, eating, and chatting like BFFs" at Perez Hilton's Blue Ball Birthday Bash. Decked out in their blue dresses, Camille, Kyle, and Real Housewives of Beverly Hills co-stars Taylor Armstrong and Adrienne Maloof posed for photos on the blue carpet.

Unfortch, Lisa Vanderpump and Kim Richards were MIA from the star-studded event, so Real Housewives of Orange County star Gretchen Rossi stepped in as honorary 90210 'Wife. "So much fun with Beverly Hills Housewives taking silly pics! Xoxo," G tweeted along with a photo of her wearing a tiara (We see you smirking, Alexis), Kyle rocking an oversized blue bow in her hair, and Taylor, Camille, and Adrienne also posing in playful sunglasses.

Those hoping for a long-term reconciliation should lace their giddiness with a dose of caution -- remember when the frienemies dressed up as 1920s flapper girls for Taylor's party and danced together like high school besties? We all know how that didn't last.
