(WJW) – John Stamos is feeling nostalgic after the birth of Ashley Olsen’s baby boy.
Last week, Ashley Olsen welcomed a son, Otto.
Stamos gushed over the twins and their impact on his life in an Instagram post this week.
“Watching Mary-Kate and Ashley grow into the incredibly bright and remarkable women they are today has been one of the greatest joys of my life,” he said. “If you would have told me those blue-eyed babies I met on set nearly 40 years ago would still be in my life at 60 years old, I wouldn’t have believed you. I am blessed.”
He shared clips of them from the “Full House” set and other events.
“I take them to Disneyland, I adore them, giving them kisses on top of their head, buy them a few crappy souvenirs and then hand them back to their parents to do the hard work,” he said in a voiceover on the video.
