Kesha's ongoing legal dispute with producer Dr. Luke takes an even darker turn. The singer now alleges her former collaborator also raped Katy Perry.

New Details Come To Light

The ongoing $50 million defamation suit against the "Rainbow" singer has just revealed details surrounding a text conversation between Kesha and Lady Gaga, during which it was suggested that Dr. Luke raped Perry.

​The exchange, which was subpoenaed as part of Dr. Luke's suit against Kesha, occurred in February 2016. ​The producer is claiming significant damages due to lost earnings as a result of Kesha's highly publicized claims of physical, emotional, and verbal abuse.

​It was widely reported in July of last year that Kesha claimed ​​Dr. Luke raped her, an allegation he continues to deny. It's now come to light that the "Praying" singer also alleged that Perry had been raped, too. Dr. Luke worked with her on hit songs including her breakout track "I Kissed A Girl" and "Teenage Dream." ​

Legal documents state that Kesha falsely accused the producer of raping Perry, leading Gaga to spread the information on social media and to the press.

"For example, in February 2016, Ms. Germanotta posted multiple articles discussing defendant defamatory statements on her Twitter page," state the documents. 

Although Perry was deposed as part of the suit, her comments to the court remain unknown. Likewise, the exact contents of the entire text conversation have not been disclosed.

A rep for Lady Gaga previously told the press that she was cooperating with the legal process and had provided all information as necessary.

"Dr. Luke's team is attempting to manipulate the truth and draw press attention to their case by exaggerating Lady Gaga's role and falsely accusing her of dodging reasonable requests," the spokesperson noted at the time .

However, the producer's legal team issued a statement to PEOPLE advising that Perry herself denied the accusations.   

"Katy Perry herself confirmed that Dr. Luke did not rape her. Kesha's accusation to the contrary - just like her other outrageous lies about Dr. Luke - is baseless and irresponsible, and it is disrespectful to both Katy Perry and Dr. Luke," it reads in part.

The Case Trundles On

Dr. Luke worked extensively with Kesha as a collaborator, particularly at the start of her career. He co-produced her breakout hit "Tik Tok," as well as follow-up "We R Who We R." Perry no longer works with him, explaining that she simply had to leave the nest to grow as an artist.

Dr. Luke's legal difficulties began all the way back in 2014, when Kesha sued him, alleging she'd been drugged and raped by the producer, as well as suffering ongoing physical and emotional abuse for the previous 10 years.

He has denied all accusations against him, countersuing his ex-charge for breach of contract and defamation. Back in February 2016, he tweeted that he'd never had any kind of romantic relationship with Kesha because she was like a little sister to him.

Kesha's abuse claims were dismissed by a judge that same year, but their dispute continues apace. She released her third album, Rainbow, last summer, in spite of still technically being tied to Dr. Luke via her recording contract with his company.

February saw her taking the Grammys stage by storm, performing "Praying" in support of the Time's Up movement alongside the likes of Cyndi Lauper, Camila Cabello, and Bebe Rexha.
