The Piece of Me hitmaker - who performed with Iggy Azalea at last year's ceremony - could be set to perform on 22 May at the T-Mobile Arena in Las Vegas as the show's producers are eager to get the pop beauty to make a massive comeback on the night. It would be ideal timing for the 34-year-old star to perform with her new single Make Me (Oooh) expected to drop two days before on 20 May.
