“Kesha accepted an invitation to perform on the show and she received written approval from Dr. Luke‘s record label, Kemosabe Records. Kemosabe subsequently rescinded its approval following a media report on Wednesday May 11 regarding Kesha’s appearance on the BBMAs. Unfortunately, Kesha and Kemosabe have since been unable to come to an agreement for Kesha to perform on the show,” Dick Clark Productions said in a statement (via Billboard).
Kesha has been in an ongoing battle with Dr. Luke to be freed from her Sony contract. Kesha has accused Dr. Luke of sexual abuse, but the courts have been siding with Sony.
