With his signature cowboy hat, acoustic guitar, and a voice built for classic country, John Foster is quickly becoming one of the most compelling breakout stars on American Idol Season 23. The 18-year-old Louisiana native once again proved his rising star power with a touching performance that left Carrie Underwood blushing and the audience cheering.

A Tribute That Hit All the Right Notes

During the live show, Foster performed an emotionally resonant version of “I Told You So,” a song famously recorded by Randy Travis and later covered by Carrie Underwood in her own celebrated career. This wasn’t just another cover — it was a deeply personal tribute to a country music idol sitting just a few feet away.

Foster’s voice rang with clarity and sincerity, striking a chord with both the judges and viewers at home. As the final notes echoed across the stage, Carrie Underwood’s reaction said it all.

“I’m blushing!” she exclaimed, smiling with pride. “Each challenge you push yourself. I love watching you grow.”

The Judges React with Unanimous Praise

The entire judging panel was quick to shower Foster with praise:

• Lionel Richie: “I am so proud of you. You killed it!”

• Luke Bryan: “Great job! You impress me so much on so many levels.”

• Carrie Underwood, touched by the tribute, even compared Foster to Dwight Yoakam — a high honor for any up-and-coming country artist.

Foster didn’t just perform the song — he connected with it, channeling his roots and raw emotion into every lyric. It was a performance that felt both classic and refreshingly personal.

A Growing Legacy of Memorable Performances

This isn’t the first time John Foster has wowed audiences. From his very first audition, where he performed a medley of George Jones’ “Don’t Rock the Jukebox” and Conway Twitty’s “Goodbye Time,” he’s shown a consistent love and respect for traditional country music.

Some of his most memorable performances so far include:

• “Neon Moon” by Brooks & Dunn

• “In Color” by Jamey Johnson

• “Callin’ Baton Rouge” by Garth Brooks

• His original song, “Tell That Angel I Love Her”

During Rock & Roll Hall of Fame Week, Foster delivered a high-energy, crowd-pleasing rendition of Elvis Presley’s “Jailhouse Rock”, showcasing not just his vocal skills but his ability to entertain. With help from guest mentor James Taylor, Foster incorporated movement and showmanship — without losing touch with his country roots.

A Rising Star in the Top 10

Now a proud member of the American Idol Top 10, Foster is proving each week that he’s more than just a country boy with a guitar — he’s a future star with stage presence, emotional depth, and a rapidly growing fanbase.

Whether or not he takes home the American Idol crown, one thing is certain:

John Foster has already won the hearts of viewers — and Carrie Underwood won’t be the only one smiling with pride.
