Billy celebrates his birthday on April 11 every year.
John Stamos shared of lovely post on his Instagram of the father and son doing adorable things together.
Even though John became a father in his fifties, he is not shy to shower his love for his only son on his social media account. It was even difficult for the actor when he had to go away from his son and wife to shoot his new series Big Shot after spending quality time with them during the lockdown.
