john stamos, olsen twins, mary-kate olsen, ashley oslen, full house, uncle jesseFull House" family -- and their Uncle Jesse has nothing but love for them, especially when it comes to big life moments.

John Stamos proved that this weekend when he shared a sweet throwback photo of him with the Olsen twins from back in their "Full House" heyday, in celebration of Mary-Kate's recent wedding to boyfriend Olivier Sarkozy. The adorable photo features Stamos sandwiched between the twins, wearing matching Mickey Mouse sunglasses and making goofy faces for the camera.

"In the blink of an eye." Congrats MK. X

"In the blink of an eye," Stamos captioned the snap. "Congrats MK."

Stamos wasn't invited to the wedding -- and it doesn't appear that any other "Full House" castmates were, either -- but that hasn't stopped the actor from wishing Mary-Kate and her sister well in the past. Though they had a brief dust-up earlier this year over the twins' knowledge of "Fuller House," they eventually patched things up.

Congrats to Mary-Kate, and cheers to Stamos for being so sweet -- and giving us some serious nostalgia.
