John Stamos has revealed his seven-year-old son, Billy, has started using his father's fame to woo girls

Stamos - who has Billy with actress wife Caitlin McHugh - told E! News: "He said, 'Dad, we had to write down all our things.'

"The girl next to him put Fuller House."

Billy soon informed the girl of her dad's role in the show.

He said: "You know, that's my dad. My dad's on that show. And he plays Uncle Jesse."

Stamos laughed: "He's using it with the girls."

The Grandfathered star went on to admit that his son likes to use catchphrases from the sitcom to "mock" his dad.

He told the outlet: "He watches Full House, but he watches it to mock me.

"Because I'll be like, 'Go put your Legos away.'"

He responded with Michelle Tanner's (played by Mary-Kate and Ashley Olsen) iconic line: "You got it, dude."

Stamos quipped: "He's pulling catchphrases on me. But mocking. Not like it's cool or anything."

Billy is his father's biggest critic.

Sharing his reaction to his father rehearsing for his part as Lock in the upcoming Nightmare Before Christmas Concert in Los Angeles, he said: "I'm doing Nightmare Before Christmas at the Hollywood Bowl, and I was just trying to learn lyrics. He says, 'Dad, put an image with it.' I said, 'Shut up.'"

He continued: "We were singing last night in the car, and he said, 'You're gonna do a different voice, right?'

"You're gonna do a higher, kind of more of a charactery voice?'"
