The "Fuller House" actor and his wife Caitin McHugh have welcomed a son into the world and have named the youngster in honour of the 54-year-old star's beloved late father, Billy.
"From now on, the best part of me will always be my wife and my son", the "Full House" star captioned the heartwarming pic, in which his son's tiny hand is holding on to his ring finger. "Welcome Billy Stamos (named after my father) #NotJustanUncleAnymore #Overjoyed", he wrote on the social media platform.
The 54-year-old, well known for playing Uncle Jesse on Full House, shared the exciting baby news on Instagram. Stamos was previously married to Rebecca Romijn. I know my parents are smiling down. "She is the most graceful person I've ever met in my life, and she's handling pregnancy like a champ".
He said: "She's so handsome pregnant".
"I don't know what I would do if I wasn't having a baby right now", he explained. "I've done every schtick you can do with a baby on TV ... all the bits and jokes and diaper gags".
John also insisted he doesn't have any nerves about becoming a dad.
