John Stamos is a terrific uncle...and an even better dad

See all of his adorable moments with his son, Billy

John Stamos, former front man of Jesse & The Rippers on the "Full House" television series, is still making beautiful music. But now he has two new bandmates.

The 60-year-old actor married model Caitlin McHugh in 2018 (his first marriage with actress Rebecca Romijn ended in 2004), and shortly after, she gave birth to their son, Billy Stamos, in April 2018.

Stamos and McHugh's meet-cute was ... errr ... more memorable than cute.

Here's how Stamos described it in a 2022 Instagram post: "I met my wife on a TV show called SVU Law and Order, where I was playing a serial reproductive abuser, trying to secretly impregnate her by poking a hole in a condom. I already had 47 children, but wanted one more. It took me 7 years, but eventually I had a child with my Disney Girl @caitlinskybound and I’ve never been happier!"

Stamos, his "Disney Girl" and their son spent their March 2020 time in quarantine singing "It's a Small World (After All)" in their pjs.

Here's everything you need to know about Billy.

Stamos announced Billy's birth on Instagram and shared that Billy is named after his father.

When Stamos introduced his son to "Full House" co-stars Bob Saget and Lori Loughlin, Billy was sporting a "Jesse & the Rippers" onesie.

Stamos sweetly captioned the photo: "The Tin Man, Dorothy and The Scarecrow say hi to the cutest of Munchkins. #BillyandtheRippers."

Saget and Loughlin weren't the only members of the "Full House" fam to welcome Billy.

Candace Cameron Bure told TODAY.com, “I know that he and Caitlin are going to be wonderful parents because they’ve been wanting this for so long. And this little boy, Billy, is going to be so well-loved." 

Stamos and McHugh were delighted by everything their newborn son did.

McHugh shared with "Entertainment Tonight" shortly after his birth: “It’s adorable. Even all the gas and stuff, everything he does is exciting. It’s like, ‘Oh yes, you pooped! That’s great! You farted, that’s great! You burped, right in my ear! You spit up in my face and I couldn’t be happier.'"

Stamos as a dad

Just by scrolling through Stamos's social media, you can see how much he adores his son.

There's the time he put baby Billy in his guitar case; when he walked Billy through Times Square in a baby carrier; the image of the fam rocking matching Christmas jammies; and the time when he competed in a father/son drum competition.

He introduced Billy to Ringo Starr, Elmo, "Fuller House," Storm Troopers, the Beach Boys, school, the Muppets, Broadway, Greek Easter, Spidey, Disneyland and of course, Mickey Mouse.

And how can we forget that time he and Billy dressed up as Uncle Jesse's idol, Elvis Presley?

Have mercy.
