The Full House family just met their newest member! John Stamos introduced his 1-month-old son Billy to costars Bob Saget and Lori Loughlin this week, and it’s all kinds of adorable.

“The Tin Man, Dorothy, and The Scarecrow say hi to the cutest of Munchkins,” Stamos captioned his photo of the hangout. In the pic, Saget and Loughlin lean in adoringly as Stamos holds up his son to show off his custom Jesse and the Rippers onesie, a nod to Uncle Jesse’s band from the Full House series.

Saget shared his excitement about meeting his longtime costar’s son on his own Instagram. “So much love, John,” he wrote, sharing Stamos’ pic. “Most beautiful boy and Mommy and Daddy ever. So proud to be a new Uncle/Tin Man, my brother.”

Two weeks ago, Loughlin sent her on-screen husband the cutest message letting him know she was ready to meet little Billy. “Hey, hey, Mr. Stamos,” Loughlin said in the clip. “We all want to come and meet Billy, but see, you’re home with a newborn baby and I’m hanging out with the cool crowd.” The When Calls the Heart star hasn’t yet shared her reaction to finally meeting the little bundle, but given the three Full and Fuller House stars’ bond — they first became a TV family 30 years ago — it seems safe to say it was a special moment for all involved.

Stamos and wife Caitlin McHugh welcomed little Billy one month ago. They tied the knot in February, after a romantic Disneyland proposal last year.
