John Foster really made waves during his American Idol audition — and it wasn’t just because of his incredible voice. At just 18, he surprised judges Luke Bryan, Lionel Richie, and Carrie Underwood by showing up with coolers full of hometown goodies from Addis, Louisiana. His Cajun roots have been a special part of his journey all season, especially when he performed “Almost There” from The Princess and the Frog during Disney Night, bringing a bit of Louisiana magic to the stage.
Foster’s been on fire all season, earning a spot in the Top 3 alongside Breanna Nix and Jamal Roberts. With the Season 23 finale coming up on May 18, the LSU student took a moment to return to his hometown, soaking in the support of family and friends.
As John’s popularity soared, fans on Facebook started guessing about his musical background — with some even thinking country star Dwight Yoakam might be his uncle. John had to clear that up himself: Dwight isn’t family.
But the real inspiration behind John’s music comes from his uncle, Gaylen Martin, a local musician who’s been his biggest supporter from day one. “I wouldn’t be a musician if it weren’t for Uncle Gaylen,” John shared with a Baton Rouge news station. “He taught me my first guitar chords when I was 15 — ‘Take Me Home, Country Roads’ — and he’s been there for me ever since.”
Gaylen has watched John grow from a curious kid into a confident performer. “He soaked up everything I taught him,” Gaylen said. “Once he got interested in guitar, he just kept going. He’s a quick learner — whatever I tell him, he picks it up right away. It’s been amazing to see.”
Seeing his nephew shine on national TV has been a proud moment for Gaylen. “He’s very teachable and hardworking. Every day he gets better, and it’s been incredible to watch.”
Even with the sudden spotlight, John is keeping his feet on the ground. Speaking to The Advocate, he said his faith and sense of purpose keep him focused. “I’m just making sure I stay true to myself and my faith,” he said. “I know why I’m here, and that’s what helps me stay balanced.”
@officialjohnfoster Lot’s of people have been asking, so here you go – some of my “uncle” *NOT* Dwight Yoakam! 😂 #JohnFoster #JohnFosteronIdol #AmericanIdol #Idol #FYP #Foryou #ClassicCountry #CountryMusic
