Kelly Clarkson filled in a “Blank Space” of her Piece by Piece Tour when she covered Taylor Swift’s standout 1989 cut while touring in Canada. The singer was performing at Toronto’s Molson Canadian Amphitheatre on Saturday when a fan requested that she sing Swift’s song. Clarkson offered up a soulful, slowed down take on the electrifyingly minimalist original. The former American Idol winner has also covered *NSYNC’s “Bye Bye Bye,” Nick Jonas’ “Jealous,” Rihanna’s “Stay,” and Imagine Dragons’ “Radioactive” on her tour.
