Not many people would move their wedding just to cheer someone on. But that’s exactly what John Foster’s sister, Elizabeth, did. When John made it to the live shows on American Idol, she postponed her own big day just to be there in the crowd, supporting him through every step.
Their mom, Amanda Binois, shared the story in an interview. She said Elizabeth flew to Los Angeles to watch John perform live, never missing a show. The video also revealed more: this was John’s third time trying out for American Idol. He had failed twice before. But he never gave up, and when he finally made it, his family made sure he didn’t stand alone.

Viewers were moved by how close the Foster family is. In the comments, fans called Elizabeth’s choice “selfless” and “beautiful.” Some even said it made them cry. Others praised John for staying humble and never quitting, even after the first two auditions didn’t go his way.
That family bond came through clearly in another moment on American Idol. During the show’s Mother’s Day episode, John performed “Believe” by Brooks & Dunn. He dedicated it to his mom. As he sang, a photo of the two of them appeared behind him, and a sign in the crowd read: “I Believe in You, Son.”
