A rep for Rathbone confirmed the pregnancy exclusively to PEOPLE in June, with the couple, who wed in 2013, telling PEOPLE, “We are over the moon for this new addition to our family, and are excited to soon be a party of five!”

Shortly after the birth of his daughter Presley in 2016, Rathbone told PEOPLE that he and Hafsadi were “open” to having more children.

“We’re going to take some time,” the actor said. “In a hypothetical sense, sure, why not? We’re open to multiple ways of having kids.”

Of his first two children, Rathbone added, “Having a boy first and then a girl, I think it’s going to make [Monroe] a better man when he grows up.”
