As of May 2025, John Foster is 18 years old, born in 2006 in the quiet, music-loving town of Addis, Louisiana. While the question of his age is straightforward, the answer opens a window into a much richer story—one of early talent, Southern roots, and national recognition. From humble beginnings to the grand finale of American Idol Season 23, John Foster has captured the hearts of millions with a voice that feels as timeless as the country genre itself.
This is the full story behind the young man everyone is talking about—not just how old is John Foster, but who he is, where he comes from, and what comes next.
John Foster: Early Life in Louisiana
John Foster was born in 2006 in Addis, Louisiana, a small town just west of Baton Rouge. Known for its sense of community and deeply embedded musical traditions, Addis provided a fitting backdrop for the rise of a future country music star. From a young age, John was drawn to the storytelling nature of country music. His household was filled with the voices of Garth Brooks, Alan Jackson, and Conway Twitty—voices that would later shape his own.
Family played an important role in John’s early years. He grew up in a supportive environment where music was a part of everyday life. Whether at family gatherings or church events, John’s voice quickly became recognized as something special. Friends and relatives recall him as a quiet, respectful child who lit up the room when he sang.

By the time he was 10, John was performing at local fairs and open mics. By 14, he was writing his own songs and sharing demos online. For those who knew him best, it was only a matter of time before the world discovered what Addis had known all along.
Influences and Style
John Foster’s voice is often described as “vintage country”—a term not used lightly in an industry that frequently favors crossover appeal. But in John’s case, the classification fits. His musical style is rooted in traditional country, marked by smooth baritone tones, clear diction, and emotional sincerity. He isn’t trying to reinvent the genre; rather, he channels its original spirit with authenticity.
His influences include Jamey Johnson, George Strait, and Brooks & Dunn, and his performances reflect their emotional precision. When John sings, listeners are transported to small towns, front porches, and late-night drives—hallmarks of country music’s emotional resonance.
During an interview on American Idol, Foster explained:
“I sing the kind of country music I grew up with—the kind that tells a story, that reminds you of something you felt before.”
American Idol Season 23 Runner-Up
In early 2025, John Foster auditioned for American Idol Season 23, then just 18 years old. He walked into the audition room with a quiet confidence and a guitar in hand. His rendition of Alan Jackson’s “Don’t Rock the Jukebox” brought immediate smiles from all three judges.
Katy Perry praised his classic tone, calling it “a breath of fresh air,” while Luke Bryan, himself a country star from Georgia, commended the honesty in John’s delivery.
From the first round, John Foster became a standout. Week after week, he performed songs that ranged from upbeat honky-tonk to heartfelt ballads. Notably, his renditions of “In Color” by Jamey Johnson and “Neon Moon” by Brooks & Dunn earned standing ovations.
Unlike many contestants who adapted their style to the week’s theme, Foster remained committed to country throughout the competition—an artistic decision that won over a loyal base of fans.
By the finale, John Foster had cemented his place as a fan favorite. Competing against Jamal Roberts—who would go on to win the season—Foster delivered one of his strongest performances of the season: “Courtesy of the Red, White and Blue” by Toby Keith, a patriotic anthem that brought tears to veterans in the live audience.
Though he finished as runner-up, Foster’s journey was far from a consolation prize. Many industry insiders now view his Idol run as a launchpad for a long and sustainable music career, much like those of previous non-winning contestants such as Chris Daughtry and Lauren Alaina.
John Foster: Quick Bio
Despite the spotlight, John Foster remains grounded. At 18, he still lives in Addis, returning home after the Idol finale to a hero’s welcome that included a parade and local celebration. His humility and gratitude are often noted by fans and peers alike.
In interviews, he often credits his parents for helping him stay focused and centered.
“They remind me that this is just the beginning,” he shared during a post-finale segment. “There’s still so much work to be done.”
Foster has not shared much about his romantic life—likely a deliberate decision to preserve some privacy. He maintains an active but modest social media presence, using his platform primarily to share music updates and thank his supporters.
He has also expressed a desire to finish high school and attend community college part-time while pursuing music, emphasizing the importance of education even amidst fame.
