Venus Williams' nickname is an absolute winner. Indeed, the professional tennis star recently revealed the adorable moniker her sister Serena Williams' children—8-year-old Alexis Olympia Ohanian Jr. and 2-year-old Adira River Ohanian, whom Serena shares with husband Alexis Ohanian—use to address her, and it’s as heartwarming as can be. In a May 2025 feature for *Us Weekly*, Venus shared, "My nieces call me Auntie Vivi." For Venus, nurturing a close bond with her nieces means everything, as she also confessed, "My proudest accomplishment is being a big sister."
Soon, Alexis and Adira will also welcome a new uncle into the family, as Venus confirmed her engagement to actor and model Andrea Preti in July. She made it official to the world during a post-match interview, exclaiming, “Yes, my fiancé is here. And he really encouraged me to keep playing.” She also revealed that her match earlier that day marked his first time watching her compete live, and it seems he might just be her lucky charm—she clinched her first singles victory in over a year.
Following that triumphant win at the 2025 Mubadala Citi DC Open, Venus kept the momentum rolling at the U.S. Open, this time with a fresh doubles partner since her sister Serena retired from professional tennis in 2022. However, Serena was thrilled to see Venus, now 45, excel alongside her 22-year-old partner, Leylah Fernandez—even if she couldn’t resist a touch of playful jealousy.
In a TikTok video posted on August 31, Serena, 43, shared a clip of the dynamic duo before their match, then turned the camera on herself, rolling her eyes with mock exasperation. Moments later, she flashed a forced smile while her eyes darted side to side. “When you see your sister @VenusWilliams has a new doubles partner @leylahanniefernandez,” Serena captioned the video on August 31, sarcastically adding, “and you are really happy she’s winning with someone else.”
Yet earlier in the tournament, Serena had expressed nothing but pride for her elder sister. “Strength, courage, determination, class, perseverance, inspiration… there’s not enough words to describe how proud I am of you @VenusWilliams,” she wrote in an Instagram post on August 26. “P.S. I hope to be like you.”
