Bow down to the queen of the covers: Kelly Clarkson.
The "Heartbeat Song" singer slowed down the upbeat song, which was requested by a fan, even giving it a little country flare, as she showed off her seriously impressive vocals. Those high notes will no doubt give you chills.
The crowd seemed to love it as they were singing along to every word, but they weren't the only ones. Taylor clearly enjoyed Kelly's cover of her VMA-nominated hit.
This isn't the first time Kelly has shown some love to Taylor. Back in 2014 she covered her hit "Shake It Off" and it's equally as good.
