"I'm very conscious that the kids who audition for 'AGT' want to be there, they're not being pushed into it, and that they're having a great day out, otherwise we wouldn't see them," he told the magazine.

Cowell had nothing but praise for 13-year-old Laura Bretan on the "America's Got Talent" Season 11 premiere on Tuesday. The teenage opera singer blew the judges away with her rendition of "Nessun Dorma."
"I have never heard anything like that in all the years I've been doing this show," Cowell said. "It was unbelievable. What made it even better is the fact that you are such a sweet person. So humble. Not even aware of how amazing you are."
