His resistance to going under the sea hasn’t stopped Billy from having a blast at his dad’s rehearsals for the show, though — even if much of his time has been spent trying to get theFuller Houseactor’s attention.
“I’m rehearsing my number, kinda for the first time on the stage — jumping on these tables, with knives and things — and all I could hear was ‘Dada! Daddy! Dada! Dada!’ ” he said in an interview withEntertainment Tonightfrom the same red carpet event.
“I said, ‘Dada’s gonna fall off the table if you don’t shut up, kid,’ ” Stamos joked.

In the meantime, Billy has been making some friends — and maybe even a few short-term enemies, much to his dad’s chagrin.
“We were doing an episode ofFuller House, and I have a friend,Josh Peck, on [the episode],” Stamos toldExtra. “His wife brings his son [Max Milo, 10 months] and my wife brings Billy, who’s never done a bad thing in his life.”
“They were taking a picture and [Billy] leans over and bites Max [on the face]. … It was horrifying! It was the first time I was disappointed in my son. It was a weird feeling,” he added, joking, “Joshnow owns my house inHidden Hills and I’m looking for a condo in Encino.”
