Keith Urban got emotional when Kelly Clarkson returned to the American Idol stage this week, and in a new interview, he explains his reaction.

Kelly shot to fame after winning the first season of Idol, and returned in its final season to say farewell and give powerful performance of “Piece by Piece,”, and could barely get through it in some spots, she was so emotional. That emotion translated to the fans and even the judges.

“This song is insane,” Keith told Entertainment Tonight. “I mean, I figure you’re either crying at this performance or you need to check your pulse. It’s an amazing song.”

Kelly is pregnant with her second child, and tried to blame her emotions on hormones. Keith joked that his reaction might have been caused by the same thing. “I was wondering if I was, too! Tears were just falling out. But it was such a…I mean, separate to her incredible gift as a singer, and the song and the performance, the humanity in that moment was just…you never see that, let alone on television. I was so grateful to be there to witness it.”

Keith will release his new album ‘Ripcord’ this year and he’ll bring his ‘Ripcord Tour’ to The Wharf with Brett Eldredge and Maren Morris on June 16.
