Serena Williams just served her beau a wedding ring!

Williams, 36, and new husband Alexis Ohanian, 34, have tied the knot after announcing their engagement in December 2016, sources tell PEOPLE. The ceremony comes just 11 weeks after the couple welcomed their baby girl, Alexis Olympia Ohanian Jr., on Sept. 1 — almost two years after they began dating in 2015.

Ohanian, the co-founder of Reddit, and Williams, one of the greatest tennis stars on the planet, wed at the Contemporary Arts Center in New Orleans in front of a slew of celebrity guests, including Beyoncé, Kim Kardashian, Eva Longoria and husband José Bastón, and fellow tennis star Caroline Wozniacki with her new fiancé, NBA player David Lee.

The nuptials happened a day after the couple took part in a star-studded rehearsal dinner at celebrity chef Emeril Lagasse‘s restaurant Meril Wednesday night. Longoria, supermodel Selita Ebanks, Colton Haynes and Cynthia Erivo were among the guests at the glitzy dinner.

Rumblings of a Big Easy wedding 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). On Thursday, crews were seen tending to chic floral arrangements and making other preparations under white tents.

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.

Shortly before the wedding, Williams’ longtime coach, Patrick Mouratoglou, wished the pair a “very happy wedding” on Instagram.

Since they went public with their engagement in December, the couple hasn’t been shy about showing their love on social media. But Ohanian first hinted at their special connection at the 2015 U.S. Open, when he was there to cheer on Williams, sharing an Instagram photo captioned: “Come at the queen, you best not miss. #USOpen.”

Williams, who has 23 singles titles to date, announced the engagement with a poem. Naturally, she posted it on Reddit.

“I came home. A little late. Someone had a bag packed for me. And a carriage waited. Destination: Rome,” Williams wrote under her personal account.

“To escort me to my very own ‘charming.’ Back to where our stars first collided. And now it was full circle. At the same table we first met by chance,” she wrote. “But by choice. Down on knee. He said 4 words. And I said yes.”

Ohanian commented on the post, along with hundreds of other Reddit users, writing, “And you made me the happiest man on the planet.”

Later, the Reddit co-founder, who has a mixed Armenian-American and German heritage, tweeted out a post of appreciation to those who congratulated them on the news of their engagement. “Thank you all for the kind words. Especially from all my Armenian brothers and sisters debating when they can claim Serena as Armenian,” he wrote.

Williams later gushed about Ohanian after her first-round victory at the Australian Open in January, complimenting the kindness of her then-fiancé.

“He’s incredibly — a really nice person,” she said. “I think he definitely treats everyone the same, which is really cool to see. Really, really nice to see.”

A few months later, in April, Williams dropped a bombshell by revealing she was 20 weeks pregnant on Snapchat, later admitting she uploaded the picture by accident!

But after that, she routinely took to social media to broadcast her baby bump:

Ohanian told Jimmy Kimmel that the two were waiting until the baby’s birth to find out the gender, though Williams already had a gut feeling on what the child might be.

“[Serena] won the Australian Open while pregnant. And she remarked that she feels like it has to be a girl because everything that that baby went through and handled like a champ, only a woman could be strong enough to take on,” he said on Jimmy Kimmel Live! in August. (Last month, Williams announced she will make her competitive comeback to tennis next January to defend her title at the 2018 Australian Open.)

Turns out, she was right: the lovebirds welcomed their daughter Alexis Jr. on Sept. 1, in West Palm Beach, Florida, and revealed her name almost two weeks later with a sweet video montage showcasing their pregnancy journey.

The new and proud parents were back on social media soon after the birth, as Williams took to Snapchat to show off her amazing post-baby body by slipping back into a pair of jean shorts:

Ohanian went to Instagram to show off how much he is a proud dad:

But Alexis Jr. has since become a bit of a social media star herself, and even has her own Instagram page (operated by her parents, of course). The account has more than 105,000 followers.

One cute photo on the page shows Alexis Jr. wearing a onesie that reads, “Smart and Strong like my Mama.”
