It feels like just yesterday we were watching two tiny toddlers with giant eyes crawl around the set of Full House. They were basically the world’s collective little sisters.

It’s a bit of a trip, right? For those of us who grew up on Passport to Paris or Our Lips Are Sealed, seeing the twins approach forty feels like a personal milestone. They aren't just "the twins" anymore; they are seasoned business moguls who have spent more than three-quarters of their lives in the public eye.
Ashley is the older one, by the way. Only by about two minutes, but in twin world, that counts for everything. They are fraternal, not identical, even though they looked enough alike to swap roles seamlessly for years.
