Sheryl kicked off the set with her debut pop smash “All I Wanna Do,” before premiering a new tune called “Shotgun.” She then invited surprise guest Blake Shelton to the stage for “Steve McQueen." Later, Sheryl and Blake’s wife Miranda Lambert swapped vocals on “Are You Strong Enough.” Brad Paisley joined Sheryl on “Real Gone” and the new tune “Waterproof Mascara,” which they co-wrote together. The set also included Sheryl’s debut country single “Easy” and her signature hit “If It Makes You Happy.”
