Embattled singer Kesha has revealed her planned Bob Dylan tribute she was due to perform at this weekend's Billboard Music Awards will not go ahead after Dr Luke's record label Kemosabe Records rescinded approval of the performance.

Taking to Instagram,the 'True Colors' singer announced:"I was very excited to perform a tribute to Bob Dylan by singing a cover of "It ain't me, babe" at the Billboard awards this year. I'm very sad and sorry to say I won't be allowed to do this.

"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. I was never going to use a picture of him, speak of him or allude to my legal situation in any way. 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."

Earlier in the week 'Billboard' reported a statement from dick clark productions, which produces the BBMAs, said: "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"Kemosabe subsequently rescinded its approval following a media report on Wednesday May 11 regarding Kesha’s appearance on the BBMAs.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."

Sad face.
