Kesha, who was preparing for a live performance at Sunday's Billboard Music Awards, is no longer performing at the show. In a statement Tuesday, Dick clark productions said that Kesha initially accepted the invitation to perform and "received written approval from Dr. Luke's record label, Kemosabe Records." But the label "rescinded its approval following a media report on Wednesday," the statement continued. "What was being planned would be a great moment and a great performance and a great song, and we hope that they can work it out because we'd really like for her to be on the show Sunday night and really show herself as the great musical artist that she is," executive producer Mark Bracco said.
