Happy Birthday, Serena Williams!

The tennis great turns 42 on Sept. 26, 2023, and some fans probably feel they’ve known her all her life.

In the spotlight from a young age thanks to her talents (and those of her big sis, Venus), Serena has grown from über-impressive kid to global champion to the actual G.O.A.T. who happens to also be a devoted wife and mother of two.

In honor of her latest milestone, check out these sweet throwback photos of Serena Williams and her sister Venus through the years.

On and off the court, Serena has talked about copying older sister Venus.

“I was like, ‘Why am I not Venus?’ And she was tired of me copying her. She was like, ‘Get your own identity, please!’ ” Serena told GQ in November 2018 about how close they were, and still are.

“🙏🏾 I promise I will stay out of your room 😒 (maybe) although I was just there getting some things I needed 🙈 ,” she ended her cheeky note, adding the hashtag “#sisters.”
