Kelly Clarkson returned to American Idol as a guest judge Thursday night for the final season.

She slayed with an emotional performance at the end of the show; there wasn’t a dry eye in the house.

Clarkson said she wrote “Piece By Piece” when she was pregnant with her daughter and now, pregnant with her son, she said she can’t help but be moved to tears when she sings this song.
