Serena Williams celebrated her retirement from tennis on Monday by letting her hair down at the launch party for Edward Enninful’s new memoir.

With more time to socialize and focus on her other business endeavors, the 23-time Grand Slam singles winner was joined by her husband Alexis Ohanian at the party in New York City.

Donning a stylish LBD for the party, Serena was seen sharing a friendly kiss with her model pal Bella Hadid as she departed the bash, thrown by Edward to celebration the publication of his book A Visible Man.

For the most part, Williams had her head down and dialed-in on her phone as Ohanian directed his attention to getting his wife into the event safely.

The entrepreneur and Reddit co-founder, 42, was all about casual-cool in the fashion department in dark blue jeans, a black dress shirt and matching sneakers.

Ohanian led the way into the entrance without and real issues, all while the cameras snapped and flashed away.

Enninful, a 50-year-old native of Ghana, has the honor of being the first Black Editor-in-Chief of British Vogue. He’s been out en force promoting his new autobiography over the last week or more, according to Metro.

Friendly moment: After spending time at the book promo event for Enninful, who’s the first Black Editor-in-Chief of British Vogue, the tennis legend made a beeline for model and gal pal Bella Hadid

After spending some time at the promotional party,  Williams, who’s turns 41 on September 26, reappeared outside and made a beeline for Hadid, who was in the backseat of an SUV that was about to drive off.

The two ladies greeted each other with respective kisses on the cheek.

Having been a hueg fan of Serena Williams over the years as both a world class athlete and a role model, Hadid got emotional and began to cry when she lost her last career match at the U.S. Open in Queens, New York.

The top model ended up being photographed shedding her tears while in the stands at the USTA Billie Jean King National Tennis Center.

Williams announced her retirement from tennis in August when she revealed she would be ‘evolving away’ from the game after the U.S. Open, which was confirmed after losing her last match.
