Mostly likely at the behest of one or both of his parents, 4-year-old Bronx recently traded in his long curly locks for a rock-star-edgy short cut that totally suits him.
And, we must say, totally makes him look like his dad. (Sure, he's got mom's flaxen hair, but there's something about that tousled side part...)
Wentz was spotting taking his little Fall Out Boy and girlfriend Meagan Camper out for lunch in Los Angeles on Wednesday.
Bronx sported a Superman T-shirt on their outing, while dad, who's apparently been taking fashion tips from Adam Levine, was out in his hole-riddled finest.
