Dr Luke says Lady Gaga accused him of rape to win an Oscar and claims Ke$ha would lie that Mick Jagger was her father and once broke into Prince's home, court documents reveal

• e-mail

Lukasz Gottwald took aim at Lady Gaga and defendant Ke$ha when he was deposed in his ongoing legal action aginst the Tik Tik songstress.

The producer, better known as Dr Luke, accused Lady Gaga of defamation after false claims began to circulate alleging that he had raped singer Katy Perry.

He also said she only went after him in a bid to win awards.

Ke$ha meanwhile was nothing but a 'liar' who drank to much according to Dr Luke, who dismissed her allegations that he had drugged and raped her when she was just 18.

The singer publicly alleged that Dr Luke drugged and raped her when she was 18 while trying to get out of her contract with the producer and parent company Sony, a bid that was denied by a judge in 2016 but is currently being appealed by the singer.

The two are also still in litigation over a lawsuit that Dr Luke filed against the pop star for breach of contract, with the producer denying he ever assaulted the singer.

Gaga's belief that Dr Luke may have raped Perry was one of the first topics during the deposition. 

Dr Luke told lawyers that he believed the entire thing was just an attempt by Lady Gaga to win an Oscar for her song from the sexual abuse documentary The Hunting Ground.

'She said just various things on her Twitter account, which has been picked up by press, media outlets,' said Dr Luke.

'She's, you know, sort of thrown my name in while trying to promote a song for her Oscar called [Til It Happens To You], about like - I think about some sort of college rape, date rape thing.' 

Dr Luke then had a difficult time naming a specific instance in which Lady Gaga publicly stated that he had raped Perry, whose name he could not remember or the stenographer incorrectly transcribed.

'I know factually because we have the conversation that she was told by Kesha that I raped Lady Carrie. I know that that is factually a lie, and I also know that since her doing that text message that Lady Gaga has been very aggressive against me in the press and in tweeting,' said Dr Luke.

'I also can just use general reasoning and just probability and say that if I heard something like that and some -  heard from somebody who claimed to know that someone raped someone, most likely, people talk.' 

He also used the question to show just how indifferent he is to Lady Gaga, stating: 'I'm thinking -I don't follow everything that - every statement that Lady Gaga makes, so I'm not - I don't own her albums. I don't go to her concerts. So I just - like I don't - I don't know every press statement she's made.'

He later claimed that there were artists and companies who refused to work with him as a result of Lady Gaga, but was only able to name one artist - Maroon 5 singer Adam Levine.

Dr Luke made claims about Ke$ha being a liar after he was questioned about her claim that he had raped her when she was a teenager. 

Her lawyer asks at one point: 'Are you aware that Ms. Sebert -  that there is evidence in the record that Ms. Sebert told doctors and medical providers that she had been raped by you prior to 2014 or prior to this lawsuit?'

DailyMail.com saw that evidence, which Dr Luke dismissed by stating: 'I don't -- in sum and substance, I think that is -- that you are wrong to say that she has spoken to multiple doctors prior to these lawsuits and said that she was raped by me. I would say that that is not a correct statement.'

It was later asked if Dr Luke had any knowledge of Ke$ha telling people he had drugged her, years prior to filing her suit. 

That was the final straw for Dr Luke.

'Kesha's a liar and Kesha lied a lot. And it was something that I spoke to her about quite a bit. And she apologized to me and admitted that she lied,' claimed Dr Luke.

'And if you're talking about the email from Jared Scharff, it also says afterwards that she - afterwards did - was completely drunk and wasted and did a tequila shot on the hood of his friend's car.'

That last comment drew the attention of Ke$ha's lawyer who asked: 'What does that have to do with anything?'

It was later asked of Dr Luke why he was so eager to work with Ke$ha if she was such a liar.

'She apologized to me. She, you know, it was one of the conditions of us moving forward and working again when she came back and wanted to work with me again,' said Dr Luke.

'And I said, "Hey, you need to make this right and you've got to be responsible and you can't just make up stories." A lot of the lies that Kesha told were sort of, I'd say, maybe non-harmful lies, like, you know, her father is Mick Jagger. About, you know, breaking into Prince's house. And, you know, like -- she had a whole lot of stories that  she would tell.'

He then said he never thought she would 'stoop so low' as lie about rape. 

'I've witnessed somebody lying about rape and making something up like that and it's disgusting. And it's -- you know, it's -- it's a horrible thing. It does incredible damage.'

He continued: 'And it's really horrible to women who actually have been raped which is a very serious, you know, serious problem. And it's disgusting. And, you know, the truth is, is I'd seen glimpses of it but never imagined it could be this bad.'

In her debut single Tik Tok, Ke$ha sang about kicking men to the curb 'unless they look like Mick Jagger.'
