On Wednesday, a source told ET that while Kesha was previously approved for the BBMAs performance by the label, once Dr. Luke saw reports that Kesha was planning to slam him in the show, the approval was rescinded.
"Kesha provided Dr. Luke with written assurances that she would not talk about him, mention him or even allude to him in her performance, but as of now Dr Luke still has not approved it," the source added. "Dr. Luke could eventually change his mind about this, however Billboard has a spot to fill for the award show and they've got five days to do it, so if a resolution isn't reached soon, it's likely there's nothing that can be done."
The cancellation of Kesha's performance
comes after her sexual assault case against Dr. Luke, whose real name is Lukasz Gottwald, was put on hold until the singer resolves her breach of contract lawsuit in New York. Kesha is accusing her former music producer of drugging and raping her, claims Dr. Luke has denied as "outright lies."
