Lady GaGa slamed Dr. Luke again on Twitter. The Mother Monster voiced her support for Ke$ha after the latter's scheduled performance at the upcoming Billboard Music Awards was blocked by Kemosabe Records which was founded by the producer.

The "Til It Happens to You" singer compared Dr. Luke to Ursula, the Disney evil villain who infamously stole Ariel's voice in "The Little Mermaid". She tweeted, "Isn't it strange that it's legal to own a woman this way? Listen Ursula, we want her voice back. #freeKesha."

Kesha was supposed to perform a Bob Dylan tribute at the BBMAs. She shared a heartbreaking message in response to the cancellation. She said the performance "has never had anything at all to do with Dr. Luke." She explained, "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."

Kesha's mother has since slammed the judge who denied the singer's request to be released from her contract with Dr. Luke's label. She also called for other artists to boycott Billboard Music Awards. "Wouldn't it be nice if other artists stood with Kesha and refused to preform if she is not allowed to sing!" she tweeted.
