Duff revealed that lately, her two-year-old son has been listening to "a lot of Hilary Duff these days" because she loves being able to share her new tracks with him. "The car stereo is always where I like to listen to my demos or songs we're almost finished with. The car radio is always like a tester, so he has to listen to me a lot," the former Lizzie McGuire star admitted.

"It's sweet because…before he hears my voice and he just hears the beginning of a song, he's like, 'Oh, momma's song!' He definitely knows what's up and he knows it's me," she shared.

So what happened when the blonde beauty showed Luca the new music video for "Chasing the Sun"? "When I showed him the video he got a little confused, which is funny," Duff smiled. "At first he was watching and then he was looking at me and looking at the TV and looking back at me, and I think he was like, 'How are you in two places at once right now?' So that was fun. It's really nice to be able to do this all over again and see him responding to it."

When they aren't testing out her new music in the car, Duff said she and Luca like to listen to Radio Disney together, which she still considers to be her "first and number one supporter."

And it appears that Luca could also have a career as a singer in the future! "We also listen to a lot of the "Cars" soundtrack. That's his jam [Rascal Flatts' 'Life is a Highway']!" The proud momma revealed, "He just learned how to do the beginning part of the song, where the person's like, 'Mmm, yeah.'"

And what's on Hilary's summer playlist? "I'm loving Magic!'s song 'Rude' and I'm kind of freakishly obsessed with Sam Smith right now. And so is Luca, actually, but he calls him 'Ham Mith' because he can't say his S'," she gushed. "I don't know if Sam would appreciate that but I think it's adorable. He's like, 'Ham Mith! Ham Mith!' I'm like, yeah, that's right!"
