John Stamos and wife welcome baby boy

"From now on, the best part of me will always be my wife and my son", he captioned the Instagram, adding the hashtags #NotJustanUncleAnymore and #Overjoyed". In the caption, the Fuller House actor noted that Billy was named after his father.

The pair announced that they had welcomed a baby boy on John's Instagram account with a precious picture of their little boy laying on his dad's chest.

Clearly, Stamos and McHugh are making their dreams come true together!

The couple had announced in December that they were expecting. The actor and Caitlin named their child Billy Stamos after John's late and beloved father Bill.

"We have the same morals and the same values, that all clicked nicely", he told People Magazine.

John Stamos is best known for playing Uncle Jesse on Full House.

Part of the reason the TV star said he feels so confident about this next stage of his life is having found "the right girl", in McHugh, 32.

While John has always wanted to be a dad, before Caitlin, he thought it wasn't in the cards for him anymore. Check out the adorable first look at young Billy Stamos, below.

John and Caitlin announced their pregnancy late previous year.
