Serena Williams playfully teased Simone Biles on Instagram after posting her own vacation video, jokingly asking the gymnast if she was jealous. Biles responded with mock devastation (complete with dramatic emojis) and a lighthearted warning that she'd get her back. It's all in good fun between two legendary athletes who clearly enjoy each other's banter.

Editor’s Note: Beyond the silly social media exchange, this tiny moment humanizes two superstars who are often seen only through the lens of their achievements. Their playful rivalry—across different sports, no less—shows how top athletes connect off the field (or mat, or court). It’s a refreshing reminder that even icons have goofy, relatable friendships.
