Awww! The 54-year-old shared an adorable black and white pic of his newborn son, Billy, sleeping peacefully on his stomach over the weekend.
John, who had been positively giddy about becoming a father, captioned the snap, “From now on, the best part of me will always be my wife and my son. Welcome Billy Stamos.” Too cute!
The actor also shared that he and his model wife named their little one after John’s father.
John also expressed his joy over the fact that he’s “not just an uncle anymore,” referring to the fact that he’s played the cool Uncle Jesse on Full House (and now its reboot, Fuller House) for ten years.
John and Caitlin welcomed little Billy as they still celebrate being newlyweds. The two got married two months ago in February.
