Are John Stamos and Zac Efron Related?

Are John Stamos and Zac Efron related? Here’s what we know about these two musical celebrities. 

John Stamos as a few surprising celebrity friends

Although he’s appeared in several television shows, Stamos is best known for his portrayal of Jesse Katsopolis, an Elvis-loving, motorcycle-riding musician in Full House and then in the Netflix spinoff series, Fuller House. Since then, however, he’s gone on to work in several film and television-related projects. 

Aside from the Full House cast, Stamos has a few celebrity friends. After working with Josh Peck on the comedy series Grandfathers and then on the Netflix spinoff series, Fuller House, these two actors became close friends, with Peck even inviting him to his wedding. 

John Stamos performed with The Beach Boys during the series, Full House. However, outside of the show, Stamos performed alongside these musicians, with them even inviting him to perform at a concert. It’s unclear if Stamos has ever met Efron, though.
