John Stamos & wife Caitlin welcome baby boy Billy

Greek American actor John Stamos and his wife Caitlin McHugh have welcomed their first child, a baby boy.

John has taken the traditional Greek path, naming his son after his late father, Billy.

The birth was announced via a picture of adorable Billy, resting on the chest of his father, who is over the moon!

"From now on, the best part of me will always be my wife and my son. Welcome Billy Stamos (named after my father)," the 54-year-old actor posted on his social media pages.

He also tagged it: '#NotJustanUncleAnymore #Overjoyed.'

Stamos, who wed model Caitlin, 31, in February has spoken of his excitement about becoming a father and said, "I've waited my whole life for this. I just can't. I'm already so emotional and so excited ... I've been dreaming about our baby. I mean, I am really excited."

Sounds like John is already what Greeks call a "Xazo Baba" (crazy in love Dad)!

Congratulations to John and Caitlin, na sas zisi!
