USA’s 23-time Grand Slam champion Serena Williams recently shared a candid moment of her life as a mother.

Williams, 45, posted this picture of herself in the back of a car, holding her daughters, Olympia, 9, and Adira, 3. Visibly exhausted, the tennis great captioned her Instagram post: “Unfiltered. Raw. Just a tired mom with a full heart holding her whole world.”
