With his cowboy hat, guitar, and a voice made for country music, American Idol rising star John Foster continues to prove he’s not just a contestant — he’s a standout talent. During the live show, the 18-year-old Louisiana native delivered a heartwarming and unforgettable tribute that left judge Carrie Underwood both smiling with pride and blushing with surprise.

Taking the stage with confidence, Foster performed a pitch-perfect rendition of “I Told You So” — a song famously covered by Carrie Underwood and originally by country legend Randy Travis. The performance wasn’t just about technical perfection — it was about emotional connection. And Foster nailed it.

As the final chords rang out, Carrie Underwood was visibly moved. “I’m blushing!” she exclaimed, visibly touched. “Each challenge you push yourself. I love watching you grow.” The crowd roared in agreement, and her fellow judges couldn’t hold back their praise either.

Lionel Richie said, “I am so proud of you. You killed it!” Luke Bryan added, “Great job! You impress me so much on so many levels.” Underwood even compared the young singer to country icon Dwight Yoakam — an enormous compliment for any country artist, especially one so early in their career.

This wasn’t the first time John Foster left America impressed. From his very first audition — a medley of George Jones’ “Don’t Rock the Jukebox” and Conway Twitty’s “Goodbye Time” — he showcased a deep love for traditional country music. Since then, he has delivered powerful performances of “Neon Moon,” “In Color,” “Callin’ Baton Rouge,” and his own original song, “Tell That Angel I Love Her.”

More recently, Foster brought down the house with a high-energy version of Elvis Presley’s “Jailhouse Rock” during Rock & Roll Hall of Fame Week. With mentorship from guest star James Taylor, Foster showed off new moves and fresh stage presence, all while staying true to his country roots. The result was a showstopping performance that had the audience on their feet and helped him secure his place in the Top 10.

Now officially part of the American Idol Season 23 Top 10, John Foster is proving week after week that he’s far more than just a country boy with a good voice. He’s a future star with heart, stage presence, and an ever-growing, passionate fanbase. Whether or not he wins it all, one thing is certain: Carrie Underwood won’t be the only one smiling with pride. All of America is watching — and rooting — for John Foster’s next big moment.
