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聽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聽given the three Full and Fuller House stars鈥櫬燽ond 鈥 they first became a TV family 30 years ago 鈥 it seems safe to say it was a special moment for all involved.
