It seems John Stamos has passed on his musical genes to his adorable 6-year-old son, Billy.
On July 7, the proud dad uploaded a video of Billy joining him onstage during The Beach Boys' recent performance at a music festival.
In the Instagram clip, Stamos played the drums while Billy sat beside him and showed off his skills during the rock band's performance of "Good Vibrations."
Billy, wearing a cute pair of lime green headphones, mimicked his dad as the actor banged on the drums.
“Had a little help from my son BILLY on good vibrations last night — Wasn’t it nice! @thebeachboys,” Stamos captioned the video.
Fans applauded the little drummer boy in the making.
"He stole the show last night!" one wrote.
Another said, "Was a great concert! So awesome that you were able to have that moment with your son."
Stamos shared more clips from The Beach Boys' performance at the Ravinia Festival in Highland Park, Illinois, on his Instagram story.
In one post, Billy watched the legendary group from the crowd and delivered his version of the floss dance.
It seems Billy gets his love of music from his dad, former front man of Jesse & The Rippers on the "Full House" television series, who still dabbles in music.
The 60-year-old actor shares his son with model Caitlin McHugh, whom he married in 2018. His first marriage with actress Rebecca Romijn ended in 2004.
A few months after saying "I do," McHugh gave birth to their son, Billy, 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!"
Throughout the years, he has frequently posted videos and photos of his family of three on Instagram. In March 2020, Stamos, his "Disney Girl" and their son spent their time in quarantine singing "It's a Small World (After All)" in their pjs.
Read on to learn more about Billy and Stamos' life as a first-time dad.
Billy Stamos
Stamos announced Billy's birth on Instagram in April 2018 and revealed that he is named after his late father, whom the actor shared a sweet tribute for in November 2021.
About a month after Billy was born, Stamos introduced his son to "Full House" co-stars Bob Saget and Lori Loughlin. He shared a photo from their first meeting which showed Billy 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 during an interview in June 2018, “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 have delighted in watching their son grow and achieve little milestones.
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 has introduced Billy to Ringo Starr, Elmo, "Fuller House," Storm Troopers, The Beach Boys (multiple times), the Muppets, Broadway, Greek Easter, Spidey, Disneyland and of course, Mickey Mouse. He also celebrated his son's first day of school in September 2021.
And how can we forget that time he and Billy dressed up as Uncle Jesse's idol, Elvis Presley?
Have mercy.
