John Stamos’ Son Billy Adorably Dons Printed Outfit as He Joins Dad in Photo Marking His Memoir’s Release Day

John Stamos' family gave their full support as he launched his new memoir. His son Billy was all smiles at the event, sporting an adorable printed outfit.

John Stamos just released his memoir titled "If You Would Have Told Me," and it was a family affair from start to finish. While preparing for the launch, Stamos signed thousands of pieces of paper to give away along with his memoir.

As he signed papers, his son Billy played around with him by riding his back and photobombing the filming with some of his toys. It took him a while to finish his work, but he and his son had a lot of fun doing it.

On launch day itself, his partner, Caitlin McHugh Stamos, proudly shared a family picture from his launch, where she added a touching post about Stamos' hard work.

In the picture, Stamos carried their son Billy while McHugh Stamos held on to them with a big smile on her face. "I am so proud of [John Stamos]. He poured his heart and soul into this book, uncovering and discovering so much about himself," she shared.

Stamos released his memoir as well as an audiobook, where he narrates the memoir from start to finish. His proud wife urged Stamos' fans to think again if they believed they already knew everything about him before reading the book.

The lovely couple is incredibly content with the family they've built. In a recent interview, the actor admitted that expanding their family wasn't in their plans.

They initially planned on having more kids, but both the actor and his wife realized "it just doesn't seem like it's in the cards." Stamos added that while their son Billy always asked for a sibling, they knew that if it actually happened, he wouldn't be able to deal with it.
