It wouldn’t have been an American Idol series finale without a show-stopping performance from the original Idol champ, Kelly Clarkson.

Despite being unable to perform live because she's close to giving birth to her second child, Clarkson prerecorded an epic medley of some of her biggest hits, and it couldn't have been more amazing.

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.

Clarkson jokingly poked fun of her epic performance on Twitter after it aired, writing, "Who's that sweaty, pregnant girl singing?? ....oh snap that's me hahaha!! #ohwell"
