Lady Gaga has been an integral supporter of Kesha throughout her rocky legal battle with Dr. Luke, and last night (May 18) the singer shared her thoughts on Kesha's nixed Billboard Music Awards performance (which was reportedly disapproved by Dr. Luke's record label).

Gaga compared the producer to a Disney villain while tweeting, "Isn't it strange that it's legal to own a woman this way? Listen Ursula, we want her voice back. #freeKesha." She also included a link with the news of Kesha's performance cancellation:

Kesha's mother, Pebe Sebert, also voiced her opinion on the decision. She wrote in a series of tweets,

"So are Keshas constitutional rights being violated now, judge Lady? Does every adult woman need a mans permission to do what she loves?...How much more public abuse does my daughter have to take before someone says " Enough is enough"!...Wouldn't it be nice if other artists stood with Kesha and refused to preform if she is not allowed to sing!"

Kesha herself came forward to update fans on Instagram, saying that her scheduled performance had nothing to do with Dr. Luke and she was planning to perform a tribute to Bob Dylan. But the #FreeKesha movement is still going on, as protesters and fans are gearing up to boycott the Billboard Music Awards, which airs live from Las Vegas on May 22.
