Eva Longoria was among the first to arrive at the rehearsal dinner held at celebrity chef Emeril Lagasse‘s restaurant Meril Wednesday night. The former Desperate Housewives actress, 42, made an appearance with her media mogul husband, José Bastón, at her side.
Tony Award-winning actress Cynthia Erivo also attended wearing a white shawl over a black dress and sporting gray-tinted hair.
Top Chef star Lagasse was also spotted at the venue on Wednesday afternoon preparing for the feast.
Williams, 36, and Ohanian, 34, are set to tie the knot in an intimate ceremony in New Orleans.
The couple are exchanging vows less than three months after the birth of their first child together, Alexis Ohanian Jr., on Sept. 1 — almost two years after they began dating in 2015.
In early November, the 23-time Grand Slam champion gathered with her friends and family for an all-out girls weekend in New York City.
The ladies went to the opulent Baccarat Hotel & Residences, the first hotel from France’s eponymous crystal brand, the luxurious weekend included five-star spa treatments, trapeze’ing, tea brunches, and dancing out on the town.
The weekend concluded with pampering by the luxurious Spa de La Mer at the Baccarat Hotel and lounging poolside in the cabanas inspired by the Côte d’Azur.
All guests wore white, with LaLa Anthony, Ciara, and the Williams sisters posing for a photo shared exclusively with PEOPLE.
Williams and Ohanian announced their engagement in December 2016. Rumblings of a wedding location started in October, when reports surfaced that the two had taken a brief trip to New Orleans to scope out potential venues (with their Yorkshire Terrier, Chip, in tow).
The nuptials also come shortly after Williams made her first red carpet appearance following baby Alexis’s birth, at the Glamour Women of the Year awards in New York City on Nov. 13. The new mom wore Versace as she presented pal Gigi Hadid with the Supernova Award.
