Martha Stewart will forever be that girl.

In a room full of New York’s most renowned chefs, Stewart reigned supreme.

The domestic diva arrived to Casa Gessi on Tuesday night for the launch of Bilt Hospitality and was “personally fêted” by the best in the industry, we’re told. Vikas Khanna, COTE’s Simon Kim, Fish Cheek’s Jen Saesue, and Bungalow’s Jimmy Rizwi, were all left a bit starstruck, a spy told Page Six.

One chef was overheard gushing, “Martha’s first-name-only famous, seeing her here had made my night.”

Guests also got a first-hand look of what’s to come on Bravo’s upcoming season of “The Real Housewives of New York City,” sans the cameras.

“Housewife” newcomer — and Bilt founder Ankur Jain’s wife — Erika Hammond, was making the rounds with her castmates, Jessel Taank and her husband Pavit Randhawa, Carole Radziwill, and Stewart’s makeup artist, Daisy Toye, who attended with her boss and Stewart’s longtime publicist bestie, Susan Magrino.

Head Chef for Team USA and a Bocuse d’Or competitor, Chef Vincenzo Loseto, provided small bites like french fries with ice cream topped with caviar, and a crab tart with fried chicken skin. Daniel Boulud introduced the Long Island native chef, who then provided the highlight of the evening: a cooking demonstration.

The event also brought out Lucali’s Mark Iacono, Lure Fishbar owner and Mercer Street Hospitality’s John McDonald, Dinex CEO Sebastien Silvestri, chef Katie Button, The Points Guy Brian Kelly, and Massimo Lusardi, who brought his wife, Uva and Nightly’s owner, Jayne Moore, as his date.
