**NEW YORK, NY (September 1, 2025)** – Tennis icon Serena Williams injected a dose of playful rivalry into the 2025 U.S. Open, posting a hilarious TikTok video reacting to her sister Venus Williams’ new doubles partnership with Canadian sensation Leylah Fernandez.

The video, posted on August 31st, showed Serena, 43, filming Venus, 45, and Fernandez, 22, during their women’s doubles match. She then turned the camera on herself, rolling her eyes and forcing a smile, before looking back and forth.

“When you see your sister @VenusWilliams has a new doubles partner @leylahanniefernandez and you are really happy she’s winning with someone else,” Serena captioned the post, dripping with tongue-in-cheek sarcasm.

The reaction comes despite Serena’s widely known support for her older sister. Just days before, she shared a heartfelt Instagram tribute to Venus after her singles loss. “Strength, courage, determination, class, perseverance, inspiration… there’s not enough words to describe how proud I am of you @VenusWilliams,” she wrote.

The Williams sisters are known for their close bond and fierce competitiveness. They have won 14 Grand Slam women’s doubles titles together. Venus has previously stated Serena as her role model, highlighting the rarity of sibling support in the high-pressure world of professional tennis.

Despite the playful ribbing, it’s clear Serena’s U.S. Open reaction was all in good fun, a lighthearted moment between two of the sport’s most legendary sisters. Tennis fans are already waiting to see if Serena appears alongside her sister in future doubles.
