Kelly Clarkson has covered a ton of artists on her World Tour -- and now, she's covering another "American Idol."

The original "Idol" hit the stage in Perth, Australia over the weekend, where she performed Season Four winner Carrie Underwood's hit "Blown Away."

"I love this song, this is probably my favorite Carrie Underwood song," Clarkson said before launching into her soulful version. "It's just super dark and I think it's super cool."

The crowd loved it ... and so do we!

But how does Kelly's cover compare to Carrie's?

Check out Underwood's live performance of the song at the Billboard Awards back in May above. Who do you think did it better?

This is only the latest of Kelly's covers. She's also performed versions of songs from Adele, Britney Spears, Katy Perry and even Eminem.
