Fuller House star John Stamos has announced the birth of his first child, a son.
Last year Stamos said he would try to be as good a father as his own was, sharing a throwback photo of himself as a baby balanced on his father's hands.
He captioned the post: "From now on, the best part of me will always be my wife and my son. Welcome Billy Stamos (named after my father) #NotJustanUncleAnymore #Overjoyed", the "Full House" star shared on Instagram, along with a snap of the newborn lying on his chest.
Stamos and McHugh, 31, got married in February after more than two years together.
John, who was previously married to Rebecca Romijn, admitted past year he'd always wanted to be a father and felt it would be a "tragedy" if he never had kids. "I'm already so emotional and so excited. I've had the most attractive blessed life on the planet, and the most honest real thing I could do, I haven't done". I know my parents are smiling down. Like, I've done everything anyone could ever.
"I don't know what I would do if I wasn't having a baby right now", he explained.
And the actor revealed that Caitlin has been dealing with her pregnancy "like a champ". "She is the most graceful person I've ever met in my life, and she's handling pregnancy like a champ".
John said: 'She's so handsome pregnant.
'Just every day I'm with her I just realise, first of all, how lucky I am, but what a special human she is.
John also insisted he doesn't have any nerves about becoming a dad. I'm not nervous about having a kid, I'm not nervous about having a kid with her'.
