Kelly Clarkson's greatest hits medley on 'Ellen': 'Miss Independent' and more
She segued into a rock-edged version of "Walk Away," proving why she absolutely deserved to win the first season of "American Idol" ten years ago.
She also worked in her hit single "Since U Been Gone" as the audience jumped up and down with her. She hit some spectacular notes and gave the ending of the song a new twist -- "now that that loser is gone," she sang.
After performing, Kelly checked out the attractions. "We spent all day yesterday at Universal Studios in Orlando and had the time of our lives! Loved the rides, LOVED all the Harry Potter stuff (especially butterbeer:), loved being on the Ellen show, and our guides were fantastic! Seriously, can't wait to go back!" she posted on Facebook.
