Katy Perry sobs during 'American Idol' audition with school shooting survivor: ‘We have to change’

Katy Perry broke down in tears during an emotional "American Idol" audition Sunday night.

Louis sang "Stone" by Whiskey Myers, and his incredible performance led to a standing ovation by Perry and her fellow judges, Lionel Richie and Luke Bryan. Emily Trainham is an entertainment editor for Fox News Digital.

After some very positive feedback, Bryan asked Louis why he was auditioning. He explained that he was from Santa Fe, and "In May of 2018, a gunman walked into my school. I was in Art Room 1, and he shot up Art Room 2 before he made his way to Art Room 1."
