John Stamos’ baby made his TV debut on a Late-Night talk show

Ready for the least surprising news you’ll hear this week? John Stamos made a really cute baby.

Fans of the “Fuller House” star have been seeing adorable photos of his son, Billy, for about six months on Instagram. But the world finally got to see him in action on TV this week.

Stamos stopped by “Jimmy Kimmel Live!” on Halloween and, in the middle of a normal interview, the 55-year-old actor surprised the host and audience by grabbing his baby from wife Caitlin McHugh and bringing him to the desk. You could tell Stamos couldn’t be more proud of his baby boy, kissing him on the cheek about a million times and asking the room, “Isn’t he the most beautiful baby?”

Kimmel couldn’t help but agree, saying, “This is the cutest baby I’ve ever seen. You’ve gotta make more of these!”

Check out the adorable moment below. Little Billy makes his entrance at about the 1:15 mark.

In case you were wondering about the very ’70s looks being rocked by everyone in that clip, Kimmel and Stamos were dressed as characters from “Welcome Back, Kotter.” McHugh and baby Billy even got in on the act, both dressing as Mork from “Mork & Mindy.”

They all nailed their costumes but it’s hard to beat Stamos with that Uncle Jesse-esque hairstyle!

Stamos and McHugh have been showing off their bundle of joy for months since his birth was announced in April. In May, Stamos showed his pride for his wife and baby by praising McHugh on her first Mother’s Day with Billy.

McHugh, 32, repaid the compliment in June by posting a sweet message for Stamos on his first Father’s Day. She said he has exceeded her already-high expectations of him as a dad.

I have a feeling we’re going to be seeing a lot more of this little guy on our TV screens in the years to come!
