May 11 (UPI) -- John Stamos introduced his son to two of his longtime co-stars this week.
Stamos is parent to Billy with his wife, actress Caitlin McHugh. He shared a photo Thursday on Instagram of himself, Saget and Loughlin sharing a sweet moment with his son.
"The Tin Man, Dorothy and The Scarecrow say hi to the cutest of Munchkins. #BillyandtheRippers," the star captioned the picture.
McHugh gave birth to Billy in April. Loughlin and several friends congratulated Stamos on becoming a dad in a video the same month.
"Hey. Hey! Mr. Stamos," Loughlin said in the clip. "We all want to come and meet Billy."
"It's so beautiful having a baby. You have to do it, Ryan!" the actor told host Ryan Seacrest.
"People are probably sick of my saying I've always wanted a kid, but you know, it just happened," he said. "I guess I was waiting for the perfect wife, which I have."
Stamos, Saget and Loughlin originally co-starred on Full House, which had an eight-season run on ABC from 1987 to 1995. Fuller House is a sequel series that focuses on D.J. Tanner (Candace Cameron Bure) and her children.
