Let's make this birthday one to remember.

78 years old (Born on April 18, 1946)

Happy birthday to the delightful Hayley Mills! From charming us all as Pollyanna, teaching generations how to find joy in every situation, to brilliantly playing twins Susan and Sharon in "The Parent Trap," you've given audiences timeless laughter and warmth. Your performances have become cherished memories that continue bringing smiles year after year.

Whether it's your mischievous antics at summer camp or your sunny optimism brightening even the gloomiest days, you remain forever young at heart. May this birthday be filled with twice the fun—just like those unforgettable twin sisters—and may happiness follow you always (no parent-trapping required)!
