In a new interview with Byrdie, the retired tennis pro and mom of two, 42, was asked what has brought her the most happiness in her life. "My kids," she responded without hesitation. "I can't say that a Wimbledon trophy holds a candle to volunteering at my kid's school." Williams shares her daughters Olympia, 6, and Adira, who was born in August 2023, with husband Alexis Ohanian, 40. The sports icon, who recently launched a new beauty brand, added that as they grow up, "I want my daughters to look at my career and learn that being authentic to themselves is really the most important thing." "I also hope my daughters see how many different passions I have — from tennis to beauty — and learn that they can lead dynamic careers and lives across their many interests," she told the outlet.
