The 54-year-old actor proposed to girlfriend Caitlin McHugh on Sunday afternoon at Disneyland by cutting together a video of some of the most romantic moments in Disney and Pixar animation, his rep tells ET. The video ended with Sebastian from The Little Mermaid encouraging Stamos to "just ask the girl."
ET has learned that Stamos' close friend, Walt Disney Company CEO Bob Iger, helped the actor pull off the romantic proposal, while Paul Briggs, the Disney Director of Feature Animation, helped pull off the special film.
McHugh, 31, did in fact say "yes" and her new fiance whisked her away to 21 Royal to celebrate with family and friends.
The Fuller House star also took to Instagram to announce his engagement. Stamos posted an illustration of him and his lady love standing in front of Disneyland's Sleeping Beauty Castle, as fireworks burst in the air.
"I asked...she said yes! ...And we lived happily ever after," Stamos captioned the pic, along with an engagement ring emoji.
"They all love her more than me. They're like, 'Is Caitlin coming?'" he joked to ET. "'We don't care about you, is Caitlin coming?'" Check out the video below to hear more about their adorable relationship.
