Have mercy – it's a boy!
John Stamos and wife Caitlin McHugh have welcomed their newborn son.
The couple named their baby boy Billy Stamos, Stamos' reps confirmed in a statement to USA TODAY. His name has a sentimental story: The 54-year-old named Billy after his late father, Bill Stamos.
Stamos posted a black-and-white photo on Instagram Monday of the baby laying on his chest. "From now on, the best part of me will always be my wife and my son," Stamos wrote in the caption. "Welcome Billy Stamos (named after my father)."
The famed Fuller House uncle has had a whirlwind romance with McHugh, 32, whom he married in February 2018. McHugh, who has appeared on The Vampire Diaries and NCIS: Los Angeles, starred in the short film, Ingenue-ish, which she co-wrote with Stamos. Their pregnancy news was announced just two months after they announced their engagement.
In December, Stamos posted a childhood photo of him with his dad, captioning the picture: "I will certainly fall short of the father my pop was, but - I’m going to give it my all!" His father died in 1998.
