Noah Guthrie -- who appeared on 12 episodes of Gleeseason six as Roderick Meeks, the first member of the rebooted glee club, New Directions -- wowed the AGT judges on Tuesday night's episode with his rendition of Rihanna's "Love on the Brain."
"I got my start doing YouTube videos. Had a little bit of a fan base from that," Guthrie, 24, told the judges before his performance. "Had a couple viral videos and things led to another and I actually ended up on a show called Glee, which was crazy."
"Bloody hell, Courtney. You’re like this shy little thing when you first came out. And then you sing and you’re like a lion," Cowell, 58, said of her performance of Otis Redding's "Hard to Handle." "I mean, genuinely incredible."
