Greyson Valor is bonding with his mom’s main squeeze!
Jenni “JWoww” Farley‘s 3-year-old son looked like a microphone natural in a video the Jersey Shore: Family Vacation star, 34, posted to her Instagram Story on Sunday — as Greyson was held by Farley’s boyfriend, Zack Clayton Carpinello.
In the first part of the sweet clip, recorded inside what appears to be a club, little Greyson (who was diagnosed with autism last year), impressively counts down from 3 before launching into the first part of the alphabet song at the encouragement of those around him.
The professional wrestler, 24, is all smiles with the 3-year-old in his arms — at one point leaning in to whisper something in the little boy’s ear as he continues to steal the show.

In a video Farley shared to Instagram, Mathews, 44, sat at a table with Greyson snoozing on his lap and Meilani in another chair.
Shortly after Farley emerged from the house carrying a mermaid-themed cake and began the gathering’s rendition of “Happy Birthday,” Carpinello exited behind her and approached the table. He then handed his girlfriend a stick lighter to light the cake’s number “5” candle so Meilani could make a wish and blow it out.
“Meilani’s 5th, wonderful day @jwoww ❤️,” Carpinello captioned a photo gallery of the birthday girl that day, which showed her in a Belle dress and playing with various Disney Princess dolls in the pool, as well as a close-up of her colorful mermaid-themed cake.

Farley and Carpinello have been dating since at least April, but he has been a friend of the family since prior to sparking a relationship with the Jersey Shore star. In fact, Greyson already had a hilarious nickname for the wrestler as of late May: “Baby.”
“He’s always like, ‘Hi, Baby!’ ” Farley told Entertainment Tonight, adding that Meilani has “always known him as [my friend] Erica’s brother, so that’s how I wanted to keep it with the kids, so it’s not an awkward transition. So they’ve just always known him as one of our really close friends.”
“I’ve spent a lot of time with the kids,” said Carpinello. “I’ve known Meilani for a few years. She’s known me for a couple years, she is great with me. I love the kids. They’re great.”
“[Meilani] honestly probably likes him more than me at this point, because he’s cooler and will do a lot more,” Farley joked to ET. “And I’m like, the mom yelling in the background. But it’s fine. I’ll let him have his moments.”
