Serena Williams, 39, was an awesome sight to see in her latest social media video! The tennis champ shared a clip of herself flaunting her incredible hair and figure while being cheeky for the camera. In the Instagram post, which she posted on Dec. 24, she’s wearing a white tank top and Daisy Dukes as she flips her long honey-colored tresses over her shoulder and gives a fierce look to whoever is filming her.
