Kelly Clarkson just proved why she’s the original American Idol winner.

On a night of nostalgia and congratulations, the season 1 champion went down memory lane, performing a medley of her greatest hits on Thursday’s series finale.

Clarkson, 33, kicked off her pre-taped mini-concert with her 2003 single “Miss Independent” then seamlessly went into “Break Away,” “Since U Been Gone” and “Because of You.”

But that’s not all. The star, who is pregnant with baby number two, also belted out her hits “Walk Away,” “My Life Would Suck Without You,” “Don’t You Wanna Stay,” “Stronger,” “Heartbreak Song” and “Invincible.”

And if that wasn’t enough, Clarkson tugged on all our heartstrings when she ended her medley with “A Moment Like This,” her coronation song after being crowned the first-ever Idol winner.

If we didn’t love her enough, Clarkson poked fun at herself right after her performance.

“Who’s that sweaty, pregnant girl singing?? ….oh snap that’s me hahaha!! #ohwell,” she tweeted.

In February, Clarkson brought on the waterworks with an emotional a Capella performance of “Piece by Piece” during Idol‘s preliminaries.
