Eighteen-year-old John Foster is no longer the quiet country kid from Addis, Louisiana—he’s officially a Top 8 finalist on Season 23 of American Idol, and fans across the country are taking notice. During the May 4 live episode themed “Iconic Women in Music,” Foster delivered a standout performance that showcased not only his rich country vocals but also his fast-rising stage presence.
Judge Luke Bryan summed it up best, saying John’s “charisma meter” was off the charts—a nod to how far he’s come since his humble audition. Carrie Underwood praised the performance, and online, fans called him the season’s “dark horse”, now barreling toward the finale with momentum on his side.
But what makes John’s journey even more inspiring is what’s happening offstage. While charming millions with his music, the LSU freshman is also taking online biology courses, working toward his dream of becoming an oncologist. “Whether I decide to pursue medicine or music full-time, I will always be involved in fighting for a cure,” he shared in a Facebook fundraiser for the American Cancer Society, proving his heart is as big as his voice.
With his family cheering him on from the studio audience, his hometown behind him, and a fanbase growing by the minute, John Foster is proving that whether it’s a mic or a stethoscope, he’s destined to make a difference.
