Kelly Clarkson Meets “Mr. Know It All” At iHeartRadio Music Festival

Kelly Clarkson is back in action, ladies and gentlemen. After a too-lengthy moment out of the spotlight, the Stronger songbird is giving her new single “Mr. Know It All” a hefty push with performances on Ellen and The Tonight Show and, most recently, by adding it to her set at the iHeartRadio Music Festival. Before beginning the number, the self-deprecating superstar joked: “I didn’t want to Downer-Debbie it with a sad ballad and grab a knife, so we’re not doing anymore ballads!” Catch the latest incarnation of “Mr. Know It All” below.
