Kelly Clarkson begins singing her emotional song “Piece by Piece” but struggles to make it to the end. With lines like “I will never leave her as you left me, and she will never have to wonder her worth”, it’s not surprising that Kelly had trouble getting through the song about her absent father. As always, Kelly’s voice was mesmerizing, but this time, it was her songwriting that left the room in bits. Her performance clearly made an impact on Keith Urban, who was seen in floods of tears as she sang.
