Dr. Luke's label blocks Kesha from performing at Billboard Awards

(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 Luke's Kemosabe Records rescinded its initial approval for Kesha to perform Dylan's "It Ain't Me, Babe" during the show.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.
    Dr. Luke, whose legal name is Lukasz Gottwald, has denied her allegations.
    Kesha added in her Instagram posting that the planned performance was not about Gottwald.
    "I was never going to use a picture of him, speak of him or allude to my legal situation in any way," she wrote "I simply wanted to sing a song I love to honor an artist I have always looked up to. thank u all for the continued support."
