John Stamos, Caitlin McHugh honeymoon at Disney World

The Fuller House star is kicking off his marriage at the happiest place on Earth!

On Saturday, Feb. 10, 2018, John Stamos took to Instagram to share a cute snapshot of himself and his pregnant wife, Caitlin McHugh, enjoying their honeymoon at Disney World in Orlando, Fla.

"#oneweek (and they said it wouldn't last) #happiestmanonearth #happiestplaceonearth @waltdisneyworld," he captioned the sweet photo of the newlyweds, in which Stamos sported Mickey Mouse ears which say "Groom," while McHugh wore Minnie Mouse bride ears and kissed him on the cheek.

And it looks like Stamos' co-stars couldn't be happier for him. Bob Saget commented on the adorable pic, saying, "Your ears have never looked happier," while Lori Loughlin, who plays Stamos' longtime on-screen wife, simply replied with two clapping hand emojis and a heart emoji.

Disney fanatic McHugh also posted a pic of herself to commemorate the trip, writing, "FixItFelixJr in Florida! #disneybound #wdw," while showing off her growing baby bump.

As Nicki Swift previously reported, Stamos, 54, and McHugh, 31, tied the knot last Saturday, Feb 3 in front of 50 guests at the Little Brown Church in Studio City, Calif. Following the intimate ceremony, the couple threw a reception in the backyard of the actor's Beverly Hills home.

The cute pair have been dating since early 2016, and they got engaged at Disneyland in late October 2017, where the Scream Queens star put together a montage of romantic Disney movie moments before popping the question. In December, the two revealed that they were expecting their first child together.

Just before the exciting announcement, Stamos told Entertainment Tonight, "It would be a tragedy if I didn't have children and I finally found the right woman — the perfect woman. I know my parents are smiling down. I know they would love her. She's a gentle, kind, graceful soul who would be a good mother."

The actor was previously married to model-actress Rebecca Romijn. They divorced in 2005 after seven years together.

Congratulations to the happy couple!
