Katy Perry has been confirmed as a performer at the 2013 MTV European Music Awards, where she'll unfurl her second "PRISM" single, "Unconditionally."

Perry, whose new album "PRISM" will hit stores on Oct. 22, has yet to release the power ballad, which has been confirmed as the follow-up to her latest Hot 100 No. 1 hit, "Roar." The pop star debuted "Roar" live at the MTV Video Music Awards in August, and trotted out album cut "Dark Horse" alongside special guest Juicy J for the first time last month.
