Katy Perry brought her hits to Las Vegas for the iHeartRadio Music Festival on Friday. In addition to singing her No. 1 single “Roar,” she shared the stage with Juicy J while performing their collaboration “Dark Horse” for the first time. Clad head to toe in black-and-white leather, the Taylor Gang rapper had the crowd bouncing along to his trippy verse.
“Turn up! Put your hands up!” he told the crowd at the MGM Grand Garden Arena.
The Dr. Luke and Max Martin-produced song is now available on iTunes and will appear on Katy’s upcoming album Prism, due Oct. 22.
