Of course, this isn't the first time (and hopefully not the last time!) that Clarkson, 33, has put her own spin on a Swift single.
We saw her perform "Shake It Off" last October in Buffalo, New York, and at the time, Swift not only shared the video, but wrote that Clarkson "slayed" the song.
Meanwhile, on Sunday, the American Idol alum tweeted at Swift, "Girl, I've been covering your songs since 'White Horse'! I love them! I wish they would have requested 'Clean' #favorite." She ended the sweet message with a happy face emoticon.

"It was an amazing cover," Jonas told ET about Clarkson’s take on the tune at the PlentiTogether LIVE concert. "We're actually touring together later this year, so it was nice to see her throwing some love my way, and I'm a big fan myself."

By covering songs, Clarkson may seem like the bigger fan, but with Swift and Jonas, they also love her work!
