Star wattage abounded in New Orleans on Thursday as A-list celebrities gathered for the wedding of tennis superstar Serena Williams and Reddit co-founder Alexis Ohanian.

Despite the media frenzy, the happy couple released few details of their ceremony. But unnamed sources told People magazine and the Daily Mail that some 250 guests were invited to the festivities at the southern US city’s Contemporary Arts Center.

 Music royalty Beyonce, legendary Vogue magazine editor-in-chief Anna Wintour, reality TV star Kim Kardashian, actress Eva Longoria and singer Ciara were all also seen arriving at the arts complex.

Security for the event, anticipated to last into the wee hours, was tight. An entire block in the Big Easy — a city known for its jazz music, good food and party atmosphere — was closed to traffic.

Williams, 36, a 23-time Grand Slam champion, and Ohanian, 34, welcomed their first child, daughter Alexis Olympia, on September 1.

They announced their engagement in December after meeting in 2015 in Rome.

Williams won this year’s Australian Open while pregnant, and is expected to defend her title in Melbourne in 2018 — just four-and-a-half months after giving birth to her child.

The Contemporary Arts Center is a large, four-story, multi-disciplinary complex boasting approximately 10,000 square feet (929 square meters) of gallery space.
