Kelly Clarkson returned to American Idol for a performance that brought the house down on Thursday, Feb. 25.
Clarkson, who’s currently expecting her second child with husband Brandon Blackstock, got emotional during her performance of “Piece By Piece.” When she cried, it was contagious, and many in the audience cried too – including judge Keith Urban.
The very first Idol winner’s emotions didn’t allow her to wait until the song was over to let it out, either. She had to stop mid-sentence and apologize for the tears.
"I'm pregnant and I'm nostalgic and I can't believe it's the last season, and I'm really sorry but I just bawled," she told host Ryan Seacrest after the performance was over and she got a standing ovation.
Clarkson also laughed, “I’m actually quite proud that I made it that far.”
