The day before Father’s Day, Fall Out Boy rocker Pete Wentz took his adorable son Bronx Mowgli along for the ride as he picked up a coffee treat at Starbucks. Pete, 31, toted his one-year-old in one hand and a handful of icy drinks in the other on June 19 in Los Angeles.

Daddy Wentz even bought animal crackers for his Converse-clad boy.

Pete married Ashlee Simpson Wentz, Bronx’s mom, in May of 2008.
