NEW YORK, NEW YORK - AUGUST 25: Andrea Preti, fiance to Venus Williams, reacts during play against Karolina Muchova of Czech Republic during their Women's Singles First Round match on Day Two of the 2025 US Open at USTA Billie Jean King National Tennis Center on August 25, 2025. Clive Brunskill/Getty Images "My fiancé is here," she told former Australian tennis player Rennae Stubbs in a post-victory interview at the time, garnering applause from the crowd. "He really encouraged me to keep playing. There were so many times where I just wanted to coast and kind of chill." Williams emphasized "how hard it is to play tennis" while crediting Preti with helping her stay motivated. "You guys don't know how much work goes into this, like, it's 9 to 5 except you're running the whole time. Lifting weights and just, like, dying, and then you repeat it the next day," she continued. "[Andrea] encouraged me to get through this, and it's wonderful to be here." When Williams mentioned that the match marked the first time Preti had watched her play professionally, Stubbs replied, "I'd say he's a good luck charm," which earned a smile and nod from Williams. Celebrity Engagements of 2025: Taylor Swift and Travis Kelce, More Prior to being linked to Preti, Williams was forthcoming about her love life, telling Cosmopolitan in September 2021 that she wasn't rushing into anything. "I have a lot of friends who don't believe me when I say that I like my life and I don't want to change it for any reason," she explained. "I'm not desperate, and they don't believe me." She added, "They say things like, 'You're going to miss your window.' I'm like, 'Please, relax. You might feel this way, but I don't. I promise you I don't.'" The following year, Williams told Glamour UK that it was "harder to get out" of her routine as a single woman than it was "to get stuck" in it. However, she felt confident that things would fall into place when she met the right person. "When life changes, you've got to know when to change," she said in the October 2022 issue. "You can't hold on to either a relationship or the singleness."
