Watch: Hilary Duff's Son Discovered Her Name Is Famous

Hilary Duff's 5-year-old son Luca may not quite understand just how famous his mom is, but according to Duff, he now knows her name.

The actress appeared on Late Night Wednesday where she revealed to host Seth Meyers that her son is starting to get a better grasp on what his mom does for a living.

"He's starting to figure out more and more," she said. "He's very funny. He's seen me on the cover of magazines in the grocery store. I really think he just thinks the next day Shane's mommy is going to be on the cover of a magazine."

Duff added that while she'd previously just been "mom," she thinks a schoolmate of Luca's may have tipped her son off.

"I think some little rascal at school told him what my name is," the Younger star said. "Luca didn't know my name, and then he said to me, 'I know your name.' And I said, 'I know.' And he [shakes head] said, 'I know your name.' And I was like, 'Ok.' And he was like, 'Hilary Duff.' "

Despite his mom's impressive accomplishments, Duff shared that Luca is still more interested in the Teenage Mutant Ninja Turtles.

"There's about nine manhole covers on every city block in New York and he wants to stop at every one of them," she revealed. "He thinks that like Leonardo and Master Splinter are down there concocting master plans to save the city. He wants to look in the tiny little holes. I'm really not that germy weird mom that's like 'Let's Purell you up from head to toe.' But like there's dog urine, probably human urine. Don't touch the ground!"
