See What Made Simon Cowell Cry On 'America's Got Talent'

You ol’ softy, Simon.

“America’s Got Talent” judge Simon Cowell was brought to tears by singer Michael Ketterer’s performance on Tuesday’s quarterfinal show.

It takes a lot to move Cowell ― and Ketterer had the chops and the emotion to do it in singing James Bay’s “Us” in the last act of the night.

Ketterer also has a moving personal story. The pediatric nurse and his wife adopted five boys from foster care to complete their family with their biological daughter.

Having previously earned a golden buzzer from Cowell to leapfrog into the live rounds, Ketterer was able to trigger Cowell’s waterworks and admiration.

“As I dad, I can’t imagine what you’ve done, and the fact that you’re on this show and you really need this. You’re a really, really special guy,” a teary Cowell said after the song.

Ketterer was asked how he could move the often-tough panelist to such a state. “I think he gets it,” the contestant said, according to “Entertainment Tonight.”

“I was trying to hold it together,” Cowell added in a post-show interview with ET.
