John Stamos loves to share his passion for music with 3-year-old son Billy.

The singer, 57, recently spoke to Entertainment Tonight about a heartwarming moment in his music career when he brought his son on stage during a performance with the Beach Boys. Stamos has been performing on and off with the popular band since 1984.

While discussing the one-of-a-kind moment, Stamos began to get choked up as he described the sweet scene.

"I had this beautiful moment last week at Petco's stadium, where he sat on my lap during 'God Only Knows' and it was like a moment that I never thought I would ever have. You know, it was nice," he shared.

Last month, Stamos opened up about some of Billy's recent milestones, including becoming potty trained.

The Big Shot actor appeared on The View where he shared that Billy just achieved the feat, but is still using the toilet in an interesting way.

"First of all, you're always trying to protect your kids so they don't kill themselves, but this how he learned to pee," Stamos said, before demonstrating on a chair behind him.

"He climbs up on the toilet like this, then pees like this," Stamos said as he perched himself horizontally on top of the chair.

"He's potty trained but I'm just afraid he's gonna smack his head on the bowl," Stamos continued. "Anyways he's a joy, the greatest highlight of my life."
