Unforgettable TV Moment: John Foster’s Emotional Serenade of Girlfriend Brooklyn With “I Cross My Heart” Brings Judges to Tears, Captivates Millions, and Sparks Nationwide Frenzy as Viewers Fall in Love With America’s Newest Heartthrob—Watch the Viral Performance That Stole the Show

On a stage filled with pressure and competition, John Foster delivered one of the most genuine moments of American Idol’s Season 23. During the Top 7 live show, Foster sang George Strait’s legendary love ballad “I Cross My Heart” but it wasn’t just for the judges or the audience at home. It was for her—Brooklyn, his girlfriend, who sat front and center in the crowd. As his voice soared through the lyrics, Brooklyn’s smile grew brighter, and the entire room seemed to hold its breath.

Foster didn’t need flashy lights or big vocals. He brought emotion, control, and pure sincerity. Carrie Underwood, who chose the song for him as part of the judge’s song challenge, knew exactly what she was doing. From the first note, Foster was completely in the zone—his country tone matched the song perfectly, and every lyric felt like it was written for him. The connection was undeniable, and the delivery? Flawless.

The reaction from the crowd—and online—was explosive. Viewers were quick to comment how this was “his moment” and “the most beautiful thing all season.” Brooklyn’s emotional expression in the audience added a layer of realness that made the performance even more moving. Judges praised it as one of his strongest yet, with Carrie calling it “perfect” and “genuine.”

If “I Cross My Heart” was John’s tender side, his earlier audition song “Goodbye Time” showed his deep connection to storytelling and country roots. It was the very song that set him on this journey—and the one that made America first fall in love.
