Want to see who is behind those babies, then
John Stamos found out he had a long lost son on Grandfathered that was played by Josh Peck who also had a son on the sitcom. Back then, both men were not married and had no children. A lot has changed since their show ended in 2016.
Stamos married Caitlin McHugh and on April 15, 2018, they welcomed their son, Billy. Eight months later, on New Year’s Eve, Peck and his wife, Paige O’Brien, also had a son named Max.
Since the two actors have a father/son like relationship, it makes sense that their boys would have an uncle/nephew relationship too. Even though they were born both in the same year.
I love when a show leads to a very special relationship for life like the one that these two have.
