Serena Williams coach, Patrick Mouratoglou, uploaded an adorable video of the tennis star playing with lightsabers with her 4-year-old daughter Olympia, drawing upon the nostalgia of the Luke Skywalker and Darth Vader duel. As the theme song by John Williams,  The Force is With You  from  Star Wars: The Rise of Skywalker , plays in the background, it's apparent the force is definitely with Olympia. The 4-year-old hilariously wears her mother down with her expert backhand and forehand, causing Williams to run away from Olympia's skillful jabs .
