Serena Williams tied the knot on Thursday in a star-studded New Orleans ceremony, making it official with new husband Alexis Ohanian. According to media reports, the lavish affair was "Beauty and the Beast" themed, and the happy crowd was peppered with some of the world's most famous faces.

A rehearsal dinner was held Wednesday night at Meril restaurant as Serena prepped for the big day. And then the true magic unfolded! The ceremony was held at the city's Contemporary Arts Center, and arriving guests were greeted with the song "Be Our Guest," a source told ET. All guests were reportedly expected to dress to the theme.

Among those guests? Beyonce, Kim Kardashian, Eva Longoria, Ciara, Kelly Rowland, Lala and of course Serena's sister Venus.

On Friday, guests are reportedly invited to the Ace Hotel where the party continues with a DJ, games and -- why not? -- a "recovery bar."

Williams and Ohanian, the co-founder of Reddit, welcomed their first child, Alexis Olympia Ohanian Jr., two months ago. They became engaged in December 2016.

"I came home. A little late. Someone had a bag packed for me. And a carriage waited. Destination: Rome, To escort me to my very own 'charming.' Back to where our stars first collided. And now it was full circle," Williams wrote at the time. "At the same table we first met by chance. But by choice. Down on knee. He said 4 words. And I said yes."
