Kelly Clarkson is currently slaying on a summer tour of the U.S. and Canada. In addition to performing hits of her own, Clarkson is pulling out a few surprises. She told Entertainment Weekly that she'll be performing a fan-requested cover at every show to give this tour a communal feeling. At an earlier stop at New York City's Radio City Music Hall, Clarkson honored a fan's request to perform a cover of Nick Jonas' "Jealous." Jonas and Clarkson are going on tour in Canada after Clarkson finishes up her U.S. dates, so it might have been a preview of what's to come. This past Sunday, Clarkson continued to wow fans with their amazing cover requests. While performing Pittsburgh’s First Niagara Pavilion, the singer gave a chilling rendition of Rihanna's "Stay." A fan managed to capture a video of the performance and post it on YouTube. Watch and listen below. You'll have it on repeat all day.
