Kelly Clarkson performed in Buffalo, New York on Saturday and decided to pay tribute to Taylor Swift. Clarkson broke into a soulful cover of Swift's "Shake It Off" during her set, which then set off screams of excitement from the crowd.
Swift saw a video of the performance on YouTube (in which you can fully see Clarkson's face, unlike the one above) and loved it. The singer, whose "1989" drops tomorrow, tweeted Saturday night.
