All Shook Up! See John Stamos & Son Perfectly Channel Elvis Presley for Billy's 1st Birthday
John Stamos and wife Caitlin McHugh's son William “Billy” Christopher celebrated his first birthday on Wednesday
In honor of his son William “Billy” Christopher’s 1st birthday on April 10, John Stamos shared a sweet photograph of the pair dressed up like Elvis Presley — a favorite singer of his Fuller House character Uncle Jesse.
“One year ago tonight, our little King was born,” the 55-year-old actor captioned the adorable father-son snap, in which they both wore matching white jumpsuits.
Giving the caption her seal of approval, Stamos’ wife Caitlin McHugh left an adoring comment, referencing The King’s classic song “Love Me Tender.”
“🎶 for my darling, i love you, and i always will 🎶,” McHugh, 32, wrote.

In her own sweet birthday post, the model and actress shared an adorable mother-son photo that showed her giving her baby boy a kiss on the cheek at Disneyland. (McHugh is an active Disneybounder, a superfan who dresses up in character at the amusement park.)
“Happiest of birthdays to my one year old son!” she wrote alongside the photo. “I am so grateful to be your mama.”

Ahead of their baby boy’s big day, Stamos and his wife revealed that they were going to throw a Curious George-themed celebration for his Billy’s 1st birthday bash.
“As much as we push Disney on the poor little guy, he loves Curious George. So we’re going to have a Curious George party,” Stamos told reporters, including PEOPLE, at Cadillac’s Oscar Celebration in Los Angeles last month.
Curious George, the eponymous character in H. A. Rey and Margret Rey’s popular children’s books, won’t just appear at the party in decorations: Stamos and McHugh were debating bringing an actual primate to the event.
“I’m starting a monkey fund now so I can get a live one,” joked the actor.
“He really wants a live monkey at our party, which I think is a liability,” added actress and model — noting that she had concerns herself.
Stamos and McHugh wed on Feb. 3, 2018, after two-and-a-half years together.
And they’ve both said they’re open to having more children, though Stamos told reporters last month that he promised his wife they would hold off until Billy’s birthday.
“She wants to wait one year, so that’s coming up,” he said after joking they’d be starting that night.
