So, you're wondering, “How old are the Osmond Brothers?” It’s a fair question, because these guys have been harmonizing their way through our lives for so long, it feels like they might be ageless—like living, breathing, singing versions of the Energizer Bunny. Let’s do the math, shall we? (Cue the abacus.)

The original sibling lineup—Alan, Wayne, Merrill, Jay, Donny, and little Jimmy—spans a pretty wild age range. Alan, the eldest, is a sprightly 75 (born in 1949). Then comes Wayne at 73 (1951), followed by Merrill at 71 (1953). Jay is 69 (1955), and of course, everyone’s favorite teen idol, Donny, is a youthful 66 (1957). Finally, Jimmy, the baby of the original bunch, is 61 (1963). Yes, you read that right: Donny Osmond is 66. Let that sink in while you sip your morning coffee and feel your own knees crack.

But hold up—don’t forget the sisters! Marie Osmond is 65 (1959), and the elder sis Virl and Tommy (who are hearing-impaired and not part of the performing group) have their own ages to boot. Talk about a family reunion that requires a spreadsheet.

Here’s the hilarious part: despite these numbers, the Osmonds still radiate that wholesome, sparkly energy from the 1970s. They’ve outlived bell-bottoms, disco, and several of their own hairstyles. Donny still performs with the vigor of a man half his age, proving that pure, earnest showmanship (and maybe a little Botox) is the real fountain of youth.

So, how old are the Osmond Brothers? Old enough to be your dad—or even your grandpa. But young enough to still make you smile. They remind us that age is just a number, especially when you’ve got a killer harmony and a closet full of sequined jumpsuits. So go ahead, cue up “One Bad Apple,” and dance like it’s 1971. After all, you’re only as old as you feel—and right now, they’re feeling about 21. And so should you.
