(CNN) Singer Kesha was looking forward to performing a Bob Dylan tribute at Sunday's Billboard Awards, but no more.
According to Billboard, Dr. Luke's Kemosabe Records rescinded its initial approval for Kesha to perform Dylan's "It Ain't Me, Babe" during the show.
"I'm very sad and sorry to say I won't be allowed to do this," Kesha said in an Instagram post. "I just wanted to make very clear that this performance was about me honoring one of my favorite songwriters of all time and has never had anything at all to do with Dr. Luke."
Kesha has been using locked in a legal battle to try and get released from her contract with Kemosabe Records and its parent company, Sony Music Entertainment, in light of her accusations that she was drugged, emotionally abused and sexually assaulted by her former producer, Dr. Luke.
