When Demi Lovato takes to the mic, you listen. This was the attitude of the entire audience at tonight's iHeartRadio Music Awards, anyway, who went silent when Demi Lovato performed "Stone Cold" alongside country music star Brad Paisley — who, oddly enough, wasn't attending the simultaneous Academy of Country Music Awards.
Wearing a Balmain blazer dress, Demi started her performance softly, accompanied only by a simple guitar and piano. As the song went on, however, she managed to give one of the most impressive vocal performances of the night, which included sets by Justin Bieber, Zayn, Meghan Trainor, and Jason Derulo.
Though she arrived on the red carpet wearing a black and white Alexander McQueen look and Prada shoes, she changed into a pique-knit double-breasted blazer dress from Balmain. Said dress is currently available at Neiman Marcus for a mere $4,800, but you can watch the whole performance (for free!) in the video above.
