She is the world’s top-ranked tennis player, while he is the distinguished host of The Late Show with graying hair.

It was no surprise who emerged victorious when David Letterman faced off against Serena Williams on a makeshift court outside the Ed Sullivan Theatre in New York on Wednesday afternoon.

In the heat of the match, her powerful strokes led to one of her balls flying off the court, shattering a window at the nearby Hello Deli. Styled with waves, her long hair complemented large hoop earrings and a lengthy chain tucked into her top during the game.

Serena, a frequent guest on The Late Show With David Letterman during the media blitz leading up to the U.S. Open tennis championships, where top players descend upon New York, first claimed the US Open title at just 17 years old in 1999. She is now aiming for her third consecutive and sixth overall victory at her home Grand Slam.

Is he hailing a cab? Looked like Letterman needed a couple of coaching sessions to hone his game

Fresh from her maiden triumph at the Western & Southern Open in Cincinnati, Serena expressed optimism about her form, stating to the press, “This level of play can definitely carry me to the (U.S. Open) title. I still have a lot of work ahead of me. It’s the best I’ve played all year, to be honest.”

In another event, Serbian tennis star Novak Djokovic appeared on The Late Show for an extensive interview with Letterman, discussing his upbringing in wаr-torn Serbia and his rivalries with Rafael Nadal and Roger Federer.

Nooo! The Late Show host registered a protest against a point

The U.S. Open, held at the USTA Billie Jean King National Tennis Center in Flushing Meadows, New York City, is scheduled from August 25 to September 8.

Later, Serena changed into a blue fit-and-flare mini-dress, unbuttoning it to revеal a black lace brа during her spirited karaoke performance at Delta Open Mic at the Arena nightclub in New York. Accessorized with white pointed-toe high heels, a white watch, and white nail polish, she charmed the crowd with her rendition of “Diamonds Are A Girl’s Best Friend,” dancing and swaying to the music in her mini dress.

Before her performance, Serena admitted to nervousness, sharing with the audience, “I’m really nervous.”

She was joined by tennis player Jack Sock, as well as stars like Laverne Cox, Uzo Aduba, Darren Criss, and Kathy Griffin at the Delta Airlines event. Serena, a devoted karaoke enthusiast, dubbed singing her favorite pastime, particularly favoring 80s and 90s rock for its compatibility with her vocal range.

Meanwhile, 21-year-old Sock delivered an energetic rendition of R. Kelly’s “Ignition,” while Laverne Cox captivated the audience with Whitney Houston’s “One Moment In Time,” playfully urging, “Please don’t put this on YouTube!”
