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鈥檚 all kinds of adorable.

鈥淭he Tin Man, Dorothy, and The Scarecrow say hi to the cutest of Munchkins,鈥 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鈥檚 band from the Full House series.

Saget shared his excitement about meeting his longtime costar鈥檚 son on his own Instagram. 鈥淪o much love, John,鈥 he wrote, sharing Stamos鈥 pic. 鈥淢ost beautiful boy and Mommy and Daddy ever. So proud to be a new Uncle/Tin Man, my brother.鈥

Two weeks ago, Loughlin sent her on-screen husband the cutest message letting him know she was ready to meet little Billy. 鈥淗ey, hey, Mr. Stamos,鈥 Loughlin said in the clip. 鈥淲e all want to come and meet Billy, but see, you鈥檙e home with a newborn baby and I鈥檓 hanging out with the cool crowd.鈥 The When Calls the Heart star hasn鈥檛 yet shared her reaction to finally meeting the little bundle, but given the three Full and Fuller House stars鈥 bond 鈥 they first became a TV family 30 years ago 鈥 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.
