The Nasty icon was scheduled to hit the stage alongside Jennifer Lopez, Sam Smith, Demi Lovato, Nick Jonas, Blake Shelton and The Weeknd at the MGM Grand Garden Arena, but has had to axe her set because of ear issues.

A representative for the singer tells, "Due to a recent ear issue preventing her from flying, she is not able to perform at the festival."

Her show in Charlotte, North Carolina on Friday (18Sep15) is still scheduled to take place, and she'll be back in Las Vegas for shows on the 9 and 10 October (15).
