John Stamos gets engaged to Caitlin McHugh at Disneyland

Have mercy!

The photo attached to the message showed a man and a woman sharing an embrace in front of a castle.

Stamos popped the question at Disneyland and used a sweet video of romantic moments from classic animated films during his proposal, his rep confirmed to ABC News.

The duo are certainly into theme parks, as McHugh has posted some nice photos of the two at Disney before.

"I’ll always be the #Mickey to his.....whatever he feels like wearing," she wrote earlier this month.

And there's this photo taken on Splash Mountain.

"There is no better way to celebrate both #Disneyland and #SplashMountain's birthdays than by riding Splash Mountain with the man who came up with the idea for the ride, the Legend #TonyBaxter !! I swear that's him behind the really enthusiastic man," she said of Stamos screaming during the ride.
