The news had been widely reported last week: Kesha was planning to make a "statement performance" about her feud with producer Dr. Luke at the Billboard Music Awards this weekend.

Unfortunately for her, Dr. Luke read that news and put the kibosh on the whole thing.

TMZ is reporting that a rep for Dick Clark Productions, the producer of the show, said Dr. Luke's label, Kemosabe Records, has been unable to reach an agreement with Kesha for her to take the stage.

Apparently Luke had originally signed off on letting Kesha perform but quickly changed his mind after hearing that she planned to make direct references to their battle on stage and possibly show pictures of her longtime producer. Luke, though, has every legal right to stop her, as Kemosabe, which is owned by Sony, still controls Kesha's music rights.

In February, a judge denied the singer's request to be let out of her contract with the label.

Kesha has alleged that Luke has been mentally and physically abusive to her over the years, including when she was pumping out her mega hits like "Tik Tok" and "Die Young."

Kesha, who walked into the courthouse as fans held up "Free Kesha" signs, had petitioned to make an album for another record company, but the judge shot her request down, encouraging her to work with a different producer, but still a Sony producer.

"All I ever wanted was to be able to make music without being afraid, scared, or abused. This case has never been about a renegotiation of my record contract - it was never about getting a bigger, or a better deal," she said. "This is about being free from my abuser. I would be willing to work with Sony if they do the right thing and break all ties that bind me to my abuser."

Kesha could still get on stage during the May 22 award show (especially if someone invites her up,) but she won't be able to perform any of her songs unless Luke changes his mind. Producers of the award show are still hoping to strike a last-minute deal.

Kesha has had plenty of big backers in her corner, including Adele and Lady Gaga, both of whom have voiced their support for her.

After accepting an award for Best British Female Solo Artist at the BRIT awards, the "Hello" singer used the stage to thank her management for letting her "embrace the fact that I am a woman". At the end of the speech, Adele said, "and I would like to take this moment to publicly support Kesha."
