Kelly Clarkson's Stripped-Down, Soulful Cover Of 'Shake It Off' Has Taylor Tweeting In All Caps

Clarkson said it's one of her favorite songs out right now.

Kelly Clarkson paid tribute to Taylor Swift in the sweetest way! At her concert in Buffalo, New York last night (October 26), an event that was originally scheduled for the grand opening of the Microsoft store at Walden Galleria, Clarkson gave Swift's "Shake It Off" a soulful, stripped-down vibe, before bursting into the peppiness of the original when it hit the chorus.

"I love that song!" Clarkson said. "Seriously, everyone gives Taylor such a hard time but she can write a hook—I'm just sayin'."

For her part, Taylor was thrilled:

And she also continued her established routine of Instagramming some more lyrics from a specific song—but this choice seemed to carry extra weight. Just a day after Katy Perry's 30th birthday, Tay Tay chose to share lyrics from "Bad Blood"—the song that's rumored to be about her falling out with Katy.

At least Kelly and Taylor have their friendship established!
