Kicking things off with "Miss Independent," Clarkson went on to effortlessly transition into her hits "Breakaway," "Since U Been Gone," "Because of You," "Walk Away," "My Life Would Suck Without Out," "Already Gone," "Don't You Wanna Stay," "Stronger (What Doesn't Kill You)," "Heartbeat Song," and "Invincible."
Finally, the 33-year-old songstress brought things home with a stirring, a capella rendition of her emotional single, "A Moment Like This," and the soulful lyrics really nailed home the importance of her performance and American Idol as a whole.
"Some people wait a lifetime for a moment like this. Some people search forever for that one special wish. Oh, I can't believe it's happening to me. Some people wait a lifetime for a moment like this," Clarkson belted, backlit by blue spotlights like the show-stealing diva she truly is.
"Thnx #AmericanIdol 4 the moment that changed my life & provided w/me a road 2 success & happiness! #blessed," she wrote, before correcting her typo in another tweet: "Haha I messed that last tweet up! I blame pregnancy! I meant 'w/me' not 'me w/' #pregnantbrain."
Finally, instead of deleting the tweet and trying again, Clarkson went on to correct her correction, tweeting, "CRAP hahaha!! I can't win with this tweet! I meant 'me w/a' meaning 'providing me with a' #whatishappening."
Give it up 4 my band!! WOOHOO!!! Thnx #AmericanIdol 4 the moment that changed my life & provided w/me a road 2 success & happiness! #blessed
