Stamos proposed to 31-year-old Caitlin McHugh at Disneyland with the actor taking to his social media to make the big announcement.
The pair then met their families for a celebration at Disney's "hidden" restaurant, 21 Royal, located in Walt Disney's old apartment on site.
The couple announced their engagement on Stamos's Instagram account with an aptly romantic cartoon drawn by Disney artist Paul Briggs. Stamos captioned a sweet sketch of the two standing in front of Sleeping Beauty Castle, complete with fireworks. "And we lived happily ever after".
"This girl I'm dating she loves this song, 'Disney Girls, ' " he said.
"No, you're supposed to marry me", responded one fan.
John Stamos is off the market - and his fans are equal parts thrilled and devastated. "Please respect my privacy during this hard time", another quipped.
This very public engagement announcement is no small thing, as the two are notoriously private about their almost two-year relationship.
Stamos was previously married to Rebecca Romijin from 1998 to 2005. They Wednesday in 1998, and their divorce was finalized in 2005.
"We like to keep our lives private because we've seen what relationships in the public eye can be like and we just like our privacy", she said. Congrats to the happy couple!
