John Foster, the 18-year-old country crooner winning hearts on American Idol 2025, delivered yet another unforgettable moment with his cover of Dwight Yoakam’s “Guitars, Cadillacs.” Performed as a tribute to his “uncle” and musical mentor, Foster’s rendition was equal parts electrifying and heartfelt — a performance that reinforced why he’s quickly becoming a fan favorite.
Originally shared as a home performance after fans drew comparisons between Foster and the country legend, his version of “Guitars, Cadillacs” proved to be more than a cover. It was a declaration of style — authentic, twangy, and brimming with charm. His smooth vocals and magnetic stage presence captured the song’s vintage country grit while infusing it with a youthful sincerity that made it feel brand new.
Throughout his Idol journey, Foster has been praised for his growth and versatility. In a recent interview with PEOPLE, judge Carrie Underwood singled him out as one of the season’s biggest evolvers. “He’s probably the one that has grown the most since he’s been here,” she said, calling him “sweet and fresh-faced,” and admitting that she feels like a proud mom watching him perform. “He reminds me a lot of my son, Isaiah. When he’s up there singing, it just melts your heart.”
Foster’s tribute to Underwood didn’t stop there. On the April 28 episode, he performed Randy Travis’ “I Told You So” — a track Underwood famously covered herself. Singing directly to her, Foster confessed the pressure he felt going into it. “She has such a great version of the song, but I knew I had to sing it to her — not just perform it,” he said. His ability to make the moment personal was deeply felt by both Underwood and viewers alike.
And it’s not just covers that are earning Foster recognition. His original song, “Tell That Angel I Love Her,” written in memory of a close friend lost in 2022, showcased his strength as a storyteller. Lionel Richie praised the young artist’s sincerity and emotional connection, noting that Foster’s authenticity is what sets him apart: “When he sings, people listen — because it comes from a real place.”
With each performance, John Foster cements his place as one of American Idol’s most compelling country voices. Whether channeling legends like Dwight Yoakam or crafting his own musical legacy, Foster’s dedication to storytelling and heartfelt delivery are winning him fans across genres. As the competition heats up, one thing is certain — John Foster’s journey is just beginning, and country music may have found its next star.
