The queen of covers has struck musical gold once again. Kelly Clarkson covered Nick Jonas' "Jealous" at her concert at Radio City Hall Thursday, and people are still obsessing over it. In a video captured by a fan, the first-season "American Idol" winner belted out the former Jonas Brothers band member's hit tune and it's still a trending topic on Facebook days later. Clarkson is known for covering a variety of tunes while on tour including, Taylor Swift's "Shake It Off" and Rihanna's "B*tch Better Have My Money." Last week, Nick Jonas joined Taylor Swift on stage at his hometown during her 1989 world tour and the two sang "Jealous" to over 65,000 audience members.
