Have mercy — John Stamos is a father.
The 54-year-old announced on Instagram the birth of his son, Billy Stamos. Stamos says the child is named after the actor's father.
Stamos says, "From now on, the best part of me will always be my wife and son."
Stamos and 31-year-old Caitlin McHugh married in February.
His publicist says "Billy and Mom are both home and healthy."
In an emotional December Instagram post, Stamos remembered his late father as he wrote about becoming a dad.
“I will certainly fall short of the father my pop was, but – I’m going to give it my all! #Balance #BillStamos#Hero,” Stamos captioned a throwback picture of the two.
“It kills me that my parents aren’t here to be part of this, but I know it probably wouldn’t be happening if they weren’t up there,” he previously told People magazine.
“You know how you put your father on a pedestal, and he’s a superhero, and then as you grow older, you go, ‘Ah, he’s just a man’? I never got to that point. Till the day he died, he was bigger than life to me.”
