Have Mercy! These Photos of John Stamos With His Son Billy Are So Dang Cute

Have mercy! I thought my crush on Uncle Jesse was serious when I was a teenager, but man, my crush on John Stamos as a dad is so much stronger. The 55-year-old welcomed his first child with his wife, Caitlin, in April 2018 and has since proven that fatherhood looks really, really good on him. Its effect on his overall glow might be even more powerful than Uncle Jesse's famous haircare routine (*gasps*).

Read through for the cutest photos of John and Billy — who was named after John's late father — but be warned: your ovaries are about to go on a wild ride.
