Sebert also called for other musicians to boycott the show.

Im very sad and sorry to say I wont be allowed to do this, 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.

Luke and his lawyers have denied all allegations in court and on social media.

So are Keshas [sic] constitutional rights being violated now, judge Lady?

Does every adult woman need a mans permission to do what she loves?

Does Kesha have the right to pursue her happiness?

Or did they only mean that for rich men?

Sony declined to comment.

Kesha and Dr. Luke did not immediately respond to EWs request for comment.
