John Foster, who finished as the runner-up on American Idol season 23, shared a message of gratitude on May 18, 2025, via his Instagram account.

American Idol Season 23 Finale premiered on May 18, 2025. The three finalists, John Foster, Breanna Nix, and Jamal Roberts, performed during the finale ceremony.

Prejean has known Foster since he was a toddler. They were neighbors for years. He remembers Foster's first performance at Morley's well — and is quick to credit the young singer's rise to his uncle, Gaylen Martin. Prejean is not alone.
