*Cue Stefon voice* The Real Housewives of New York's 10 year anniversary party had everything. Dina Lohan pouting in a corner. A Countess. The Fat Jew's gravity-defying braid. Free flowing tequila. And a Sonja Sir Mix-a-Lot (that's the thing when Sonja Morgan goes wild in a sea of flashbulbs while dancing to "Baby Got Back"). Needless to say, it was THE place to be for the premiere of RHONY's 10th season.

Housewives and Bravo A-listers got turnt at The Seville, the new subterranean lounge at The James Hotel. Featuring gilded accents, plenty of plush banquettes, and a bar that stretches an entire side of the room, the luxe spot was the perfect place to celebrate such a huge milestone.

Tinsley Mortimer, as always, kept things chic in a black, collared frock, while Ramona Singer, Dorinda Medley and Carole Radziwill went a decidedly glitzy route with their ensembles. Though a back VIP room allowed the stars some privacy, they were hardly standoffish, happily mixing and mingling with guests including Andy Cohen and The Fat Jew. Dorinda, for one, took selfies with practically every fan in the room and posed excitedly next to a flat screen TV when she appeared on the show dressed as Lady Gaga. #ICONIC.

We're sure the open bar didn't hurt the high spirits. Bottles of Tequila Avión and White Girl Rosé were being popped left and right. Certainly the appropriate choices of booze to toast to this crew. Click through for a look at what you missed!
