Let's make this birthday one to remember.

81 years old (Born on November 22, 1943)

Happy Birthday to the legendary Billie Jean King! With 12 Grand Slam singles titles, 16 women's doubles crowns, and another 11 mixed doubles championships under your belt—honestly, we're exhausted just counting them—you've truly aced life. Your iconic victory in the "Battle of the Sexes" match against Bobby Riggs still makes us smile; after all these years, it's clear you didn't just win a tennis match—you won history.

Thanks for smashing barriers both on and off court with unmatched style and humor. May your birthday be filled with laughter as timeless as your legacy—and cake sweeter than any championship trophy!
