Kelly admits she was "so embarrassed" after her performance on Idol.
After making everyone cry on American Idol, Kelly visited Ellen to perform her emotional track.
Last week, Kelly Clarkson made headlines when she returned to the stage that made her a star to perform "Piece By Piece", a touching song about being abandoned by her father and finally finding love and security with her husband, Brandon Blackstock. Her performance was so impactful and emotional that it brought everyone, including Kelly, to tears and launched the song, which was released over a year ago, to the top of the iTunes charts.
Today, the American Idol winner made an appearance on The Ellen Degeneres Show to perform the song once again and to talk about her captivating Idol performance. She admits that she was "so embarrassed" following her performance of the song which she calls "incredibly sad but hopeful" and explains why she had so much trouble keeping it together.
