For the NCIS star, being a father has provided “a sense of purpose that is hard to describe.”

“Like, you could in fact lift a car, if you had to,” he previously told PEOPLE. “Personally, being a girl dad has been the most fulfilling feeling. As an artist, it has also fueled me to make sure she has so many stories in which she sees herself as the hero of her journey. All in all, I was born to be a dad.”

The couple also said that Nakano was the first to know about the family’s new addition.

“She read [the results of the pregnancy test] to Wilmer and I, and she has been shouting it from the mountaintops to every person who comes in her path: ‘I’m going to be a big sister!’ ” Pacheco said at the time.

Valderrama added that Nakano had also “been so sweet” to Pacheco amid her second pregnancy.
