What’s poppin’? Louisville native and rapper Jack Harlow stopped by eight different Jefferson County Public Schools on Thursday, according to JCPS spokesperson Carolyn Callahan . As he’s been coined, the hometown hero offered advice, answered questions and took selfies with stunned students. “It was a really great experience for students to have Jack Harlow come back to JCPS,” Callahan told the Courier Journal . “He told them to always work hard and push themselves to keep getting better at what they love to do.”
