Earlier this week it was confirmed that Kesha will no longer be able to perform at the Billboard Music Awards after Dr. Luke's label Kemosabe Records revoked its permission initially given to her. 

A statement from Dick Clark Productions explained that she is no longer legally allowed to perform at the ceremony on May 22 and hopefully an agreement might be reached before the event takes place:

"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 Kemosabe subsequently rescinded its approval following a media report on Wednesday May 11 regarding Kesha’s appearance on the BBMAs.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."

Kesha's mother Pebe has now hit out at the unfair ruling in a series of tweets, which read: "So are Kesha's 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? Do you think that there is one male singer who could ever be 'not allowed to sing' on the Billboard Awards by another man??? How much more public abuse does my daughter have to take before someone says 'Enough is enough'!"

Pop sensation and award-winning actress Lady Gaga also rushed to defend Kesha, tweeted a message alongside a link to a story about Dr. Luke blocking Kesha's appearance at the awards that read, "Isn't it strange that it's legal to own a woman this way?"
