28 Photos of MK & A, From 1986 to Today

Happy birthday to the Olsen twins! Can you believe that these two ladies are 28-year-old ladies? Mary-Kate and Ashley Olsen have really grown up. From their start as non-speaking cute babies on Full House to their detective work as 8-year-olds to their musical attempts ("I Am The Cute One," anyone?) to their low moments with the tabloids to Mary-Kate's enormous engagement ring to being full-fledged business moguls and fashion mavens, not only did they grow up in front of our eyes, but a lot of us have grown up with them, too.

So what better way to celebrate their 28th birthday than by looking back at how much they've grown up, year by year? From matching outfits to...well, matching outfits (black is the new orange, in their case), they're two of the few celebrities we've seen completely transform. And honestly, they're two celebs who prove that being a child star doesn't necessarily mean you're doomed as an adult. These two are trailblazers, I tell you.

Let's take a stroll down memory lane and commemorate these two women. Even if they want to admonish their musical history, they both were the cute ones, and they both are the gorgeous ones now.

1986 — These girls are born!

1994 — The Case of The "Logical I" Ranch

Directly from The Adventures of Mary Kate and Ashley. You had the boxed VHS, right?

1995 — "Gimme Pizza" from You're Invited!

You can, indeed, put anything on a pizza, as we learned from these two girl's sleepover party that we sure as hell wish we had been invited to.

And also, this movie came out in 1995. Remember? Of course you do.

1996 — They're getting so big!

Still keepin' up with those VHS movies.

This mall party was probably the party Robin Sparkles wishes she attended in Canada.
