Serena Williams had a racket in her hand once again, but this time it was to introduce her youngest daughter to her favorite game. Williams, 44, shared a series of photos via Instagram on Monday, November 24, showing her teaching the game to daughter Adira, 2. (Williams and husband Alexis Ohanian also share daughter Olympia, 8.) "This is me sharing my passion for tennis with my youngest daughter," Williams wrote in the caption. In the photos, Adira had a racket of her own and looked to be getting some early lessons from mom, who was showing her the proper form.
