At just 6 years old, Ashlee Simpson‘s son Bronx Mowgli is already showing signs that his parents’ musical talents have been passed on.
“He’s so into music,” Simpson, 31, tells PEOPLE of her son with ex-husband Pete Wentz. “He loves to dance around and he writes little songs. They’re good! It’s so cute.”
Bronx might even get a taste of being a rock star thanks to a present it sounds like he’s getting for his seventh birthday next month.
Adds Simpson: “He’s super into video games and this one is perfect for him.”
If he does get the gift, Bronx will have a guaranteed audience: his 11-week-old little sister Jagger Snow.
“He dances for her and entertains her,” Simpson recently told PEOPLE. “Bronx is such a good big brother. He’s a pro.”
