John Stamos Spotted with Wife Caitlin and 1-Year-Old Son While Preparing for 'A Capitol Fourth' (Photo)

John Stamos’ hosting gig for PBS’ “A Capitol Fourth” this year was a family affair as the actor/singer was spotted in the company of his wife Caitlin McHugh Stamos and their son William “Billy” Christopher while getting ready on the West Lawn in Washington, DC.

Third time’s the charm for Stamos who hosted the annual PBS Independence day concert for the third consecutive year and what better way to do it than with family?

The "Fuller House" star was photographed on July 3 holding Billy in his arms on the West Lawn where rehearsals were ongoing. One-year-old Billy was waving two American flags.

We owe them a great debt of gratitude for their sacrifice that affords you ...the chance to be anything you want

Although it wasn’t even July 4th, the Stamos clan came prepared in their ensembles. The “General Hospital” star wore a dark blue suit while Billy wore a shirt of the same color in a lighter shade. Caitlin, on the other hand, balanced things up with a red-and-white striped outfit.

This year’s “A Capitol Fourth” concert special, according to PEOPLE, featured a star-studded lineup including Gospel artist Yolanda Adams, singer-songwriters Carole King and Colbie Caillat, “The Voice” winner Maelyn Jarmon and many more.

The event also featured a 50th-anniversary tribute to Sesame Street, with appearances by some of the series’ famous Muppets like Big Bird, Elmo, and Bert & Ernie.

In a previous interview with Fox News, Stamos, 55, emphasized the importance of family in this year’s celebrations.

"I think it's a celebration of family, but also, what does it mean to be an American? What does it mean to be in America certainly right now you know? And you know what does it mean to be an immigrant that's here?”

“What does an American mean to you?” he continued. “And I think it's sort of different for everybody, but I think it's a time to stop and reflect and sort of really think about the importance of being an American and an American family.”

Stamos’ emphasis on the celebration of family rings true with the emotional tribute he paid his son (who was then three months old) while hosting the concert last year.

“You [Billy] were blessed to be born in the greatest country in the world and that makes me the luckiest father in the world. I'm gonna teach you to always thank the men and women in uniform, who keep us safe and secure and free. We owe them a great debt of gratitude for their sacrifice that affords you, my son, the chance to be anything you want to be, maybe even a soldier one day.”

“Most importantly, son, I'm gonna teach you to always celebrate this day as our nation's founders wanted us to — together as a great American family united in love of our country,” Stamos added.
