John Stamos Shares Sweet Throwback Pic With Elizabeth Olsen: 'They Grow Up So Fast'

John Stamos is loveable for many, many different reasons. Yes, he's gorgeous and yes, he was everyone's crush as uncle Jesse on Full House. But, what I love the most about this Greek God is he is nostalgic AF! His Instagram is filled with throwback pics and behind-the-scenes moments that are almost too sweet for words!

Now, his latest post dedicated to Elizabeth Olsen might be my new favorite.

It was very shocking to learn that many people didn't realize *WandaVision* star Elizabeth Olsen was the younger sister of Mary-Kate and Ashley Olsen.

You know, MK + Ash, the dynamic duo of fraternal twins that essentially invented pop culture for an entire generation.

One of the most iconic performances given by the Olsen twins was their joint performance as Michelle from *Full House* which, of course, starred John Stamos.

Their friendship goes way back, which means John has known Elizabeth for decades, too!

Now, John is posting a sweet throwback pic to celebrate the 32-year-olds hit Disney+ series WandaVision and his upcoming Disney+ movie, Big Shot.

"One day she’s a little girl wandering the set, and next thing you know, she’s taking over a whole town, mindcontrolling the citizens to play out her favorite TV Sitcoms!" John captioned the pic.

"They grow up so fast... Wanda had a vision we’d both be on @disneyplus Check out #BigShot coming in April and @wandavision Tonight!"

"Oh that's iconic" commented one fan.

"Two beautiful ppl. Love it! Get it Liz! And Uncle Jesse, you are ageless," commented another.

"That’s some strong DNA in the Olsen home." echoed a different user.

Aw, I love that uncle Jesse is truly EVERYONE'S uncle in real life, too!
