Looks like Hilary Duff might have a future Ghostbuster on her hands!

On Wednesday, the actress and singer posted an adorable video to Instagram. In it, her 4-year-old son Luca Cruz gives the original singers of the franchise’s famous theme song a run for their money.

“Who ya gonna call?!” the blond cutie begins, before pausing to start over. “I mean, I mean … something strange, in the neighborhood, who ya gonna call? Ghostbusters!”

“Woo, so good!” Duff, 28, praises her son after he delivers the lyrics perfectly.

“Guys! I don’t love to put my kid on blast but this is just too good!” the proud mom addresses her followers in the clip’s caption, adding on multiple heart emojis and tacking on the hashtags “#Ivewatchedit200times,” “#thiswillbeshownathiswedding,” “#ghostbusters,” “#whoyagunnacall” and, of course, “#lucanailedit.”

Singing is just one of Duff and ex-husband Mike Comrie‘s talented little boy‘s creative outlets: According to his mom, he’s also quite the storyteller.

“He is really creative with his play and the stories that he’ll come up with,” the Younger actress told PEOPLE in June. “I do it a lot with him, so I think it’s helped him learn how to do it, but sometimes the things he comes up with are really creative.”

And Ghostbusters isn’t the only franchise Luca is a big fan of.

“His storylines — like if he’s being Leo, the blue Ninja Turtle, and Shredder, he’ll be like, ‘No, you can’t eat that pizza right now because the bad guys are coming,’ and then he’s like, ‘Okay, I’ll get my nunchucks, be right back,’ ” Duff added. “Just all the details.”
