Lady Gaga and Kelly Clarkson both spoke about their distaste for music producer Lukasz Gottwald in depositions given during the ongoing lawsuit between the man better known as Dr Luke and Ke$ha that have been obtained by DailyMail.com.

In her deposition, Gaga alternated between sobbing and angrily responding to questions about rape and the sexual assault of women, including one about fellow pop star Katy Perry.

Gaga confirmed to lawyers for Dr Luke that she and Kesha had been told by Interscope Chairman John Janick that Perry was sexually assaulted by the producer, an allegation that Perry herself later denied under oath.

Meanwhile, Kelly Clarkson made it very clear how little she cared for Dr Luke in her deposition, saying she found him to be 'bullying' and 'demeaning.'

She also detailed how she told him off back in 2008 during the third and final time she was forced to work with the producer.

Ke$ha 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.

At the start of Gaga's deposition, her lawyer made an announcement on the record.

'I just want everyone to understand that, as she has publicly stated in other contexts, as a sex abuse survivor, and I know this from my own personal experience with family members, there are trigger events, and this deposition has proved to be a trigger event for Ms. Germanotta, and she has experienced in the past few hours some PTSD reactions which is causing some trauma and emotional reactivity,' said the attorney.

'So she is crying now the record will reflect. That doesn't mean she is unable to testify truthfully and competently, and she is prepared to do so, but I just want the record to reflect that she is in a state of emotional upset and may need, from time to time, even though we all share the interest of getting this deposition done as expeditiously and efficiently as possible, may need to just take some breaks.'

It was also revealed at the start that Dr Luke was listening to the deposition remotely.

Gaga said early into her deposition that Janick told her the rumor about Perry and Dr Luke while the pair were having a conversation about bringing Ke$ha over to their record label, Interscope.

'[Janick] was there to be supportive to her, and I had a conversation with him and her about what we can do to speak with Sony about potentially maybe bringing her over to Interscope, and that I would look after her,' said Gaga.

Lawyers for Dr Luke then began to ask questions of Gaga that appeared to suggest there was a sinister or vindictive motive to the comments she and KeSha had made about the alleged assault involving Perry.

Gaga was very quick to shoot that down, stating: 'I was really and truly trying to be supportive of her and listen to her. It is my personal opinion with rape survivor that it's very difficult to come forward, and if she hadn't come forward or if she hadn't told me herself or I hadn't seen anything, I would never make an assumption like that as someone that works in that space and that advocates for women who are sexual assault survivors.'

She added: 'I was speaking with Kesha in a very casual personal way so that I can help her feel not alone.'

Gaga said she would run into Ke$ha from time-to-time when the were starting out in the industry and they had grown close as a result.

She also recalled running into the singer at Dr Luke's home studio once, where Ke$ha was 'in the back in her underwear on a bed.'

The deposition then grew intense as questions started to arise about the damage Ke$ha's rape allegations had on Dr Luke.

Gaga remained remarkably composed for the start of that round of questions, but tensions quickly began to rise.

As lawyers for Dr Luke focused in the rights of the accused, Gaga at one point stated: 'And when this happens in this industry, it is kept extremely secret, and it is compounded by contracts and manipulative power scenarios that actually include this very situation that we are all in right now.'

Dr Luke's lawyer responded by asking: 'But, again, there are people that are falsely accused of rape, aren't there? You think there has never been a false accusation of rape?'

Gaga was advised at that point to stop responding but ignored the advice of counsel, saying: 'You - how about all of the women that are accused of being liars and how she was slut shamed in front of the world, how about that?'

The singer was then asked to answer a theoretical question about her father being accused of rape and whom she would believe in that instance.

The lawyer for Dr Luke said she would believe her father, to which Gaga fired back: 'How would I know my father didn't do it?'

She later added during the same line of questions: 'If my father did it, then he did it.'

Gaga then cut to the chase and informed the lawyers that she 'believed' Kesha, saying: 'Why on earth would this girl tell the entire world that this happened? Why on earth? Do you know what it's like for survivors? Do you know what it's like to tell people?'

She then lashed out at the lawyer, saying: 'Don't you roll your eyes at me. You should be ashamed of yourself.'

A recess was called after that, and the deposition once the parties returned did not break any new ground.

The focus became her tweets and texts with Ke$ha, which Gaga defended despite arguments that suggested they were part of a vicious campaign against Dr Luke.

'My external postings are not meant in any way to damage anyone's reputation. All of my postings, all of my retweets were in the spirit of informing young women around the world, of giving a voice to somebody that needed a voice, because she is a sexual assault survivor, and she deserves to have a voice,' said Gaga.

'It was in service of not only the music industry community but of the sexual assault survivor community, and I was steadfastly passionate about making sure that she never felt alone.'

Clarkson's deposition was far less combative, unlike her relationship with Dr Luke.

The two first worked together on Since U Been Gone, then Behind These Hazel Eyes before their third and final song, My Life Would Suck Without You.

That third session is when Clarkson went off on Dr Luke.

'He walked up to me, and I was standing with my manager Narville Blackstock, not to be confused with my husband, who is also named Narville, but he goes by Brandon,' explained Clarkson.

'He is my father-in-law, it's very incestual. But he was standing next to me, my manager, we were talking. And Dr Luke attempted to come up, or he didn't attempt. He came up and said, "hey, you know, I don't know like what the problem is, you know, between us."'

Clarkson, who has never been much for artifice, did not let Dr Luke explain any further, she told lawyers.

'And I just cut him off and said, "man, you know exactly what the problem is between us. You know, like things that have gone down behind the scenes." And, you know, via my label, via people telling me at my label like things he said and just his way of like having arguments with my fans and having like just his person,' said Clarkson.

'Like I was like, "you know I don't like you. And it's cool like I don't have to like you, you don't have to like me. There's plenty of people in the world like and, you know, I hope you're successful in your ventures. I'm going to be successful in mine. We don't have to work together. You know why I'm here; I have to be." I was like so there's no -- I'm like, "I'm not mad about it, I'm not angry, I just don't want you in my life." So... '

When asked how Dr Luke responded to that, Clarkson recalled: 'He said, I mean, well, he was in disbelief, which is pure Dr Luke fashion when he does something that isn't nice.

'And then is like "what" and he just kind of chuckled and laughed and walked off.'

Clarkson was then asked: 'Did you have any interactions with Dr Luke after that?'

To that The Voice host quickly responded: 'Not one.'

Clarkson also revealed during her deposition that she was one of many women in the industry who did not enjoy working with Dr Luke.

'I have heard, I think it's P!nk and I have heard like doesn't like working with him. I have been told,' said Clarkson.

'I was not told this via P!nk. I was told via my label because they're like, you know, we're having a hard time with him working with other people. And then they said, actually almost every female at our label doesn't like working with him.'

She said that a big reason she did not care for the producer was because he falsely took credit for her work, leading to a tense meeting with music legend Clive Davis.

'I was told by my label executive, it was a really rough meeting, Clive Davis, where first of all, he told me I was a s****y writer and that I shouldn't -- I should just shut up and listen to the producers. And then he said, and I said or he said something about hits. You should just take the hits and just sing them or something to that extent,' said Clarkson.

'And I said, well, I'm a writer on these. I mean, I wrote on Miss Independent. I wrote on like Hazel Eyes. I wrote Because Of You myself. Like I wrote, like I'm like, and then he proceeded to say that I did not.

'Well, he told me I was lying. That Dr Luke told him that he had written Hazel Eyes. And I was like, I'm pretty sure I went through a real s****y relationship. Can I say s****y? those situations. And especially to label heads who just look at a lot of women as a piece of ass selling music. So, you know, it was, I was pretty mad about it.'

The entire incident was all the more difficult because of the work Clarkson was putting into her music.

'To write those lyrics, you know. So it was kind of, it's pretty, I mean, I'm known for being a singer. So it's hurtful whenever you try so hard and you have been accomplished in a certain area. And then somebody just lies about their part in a song. And I said, well, we definitely did collaborate. But I can pull out the lyrics from a notebook piece of paper that I still have. I was like, what?' said Clarkson.

'So it just, you know, and I wasn't there when Dr Luke apparently had a conversation with Clive but. And then there was another circumstance, and I'm not remembering it right now, but there were a couple of circumstances. That was the main one. That really frankly pissed me off. A. Because he was demeaning -- he was, as a writer, he was undermining me. And it's like, well, I mean, I'm aware I have a good voice, but I'm also a good writer. And for somebody that's trying to make it so hard in an industry like himself at the time because he had not had success before Since U Been Gone. So you'd think that person would understand how important credit is in.'

KeSha has been in litigation with Dr Luke since 2014, and in 2016 said in an open letter: '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.

'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.'

Shortly after she posted that message Adele acknowledged her legal troubles at the Brit Awards in London, choking up as she said; 'And I would like to take this moment to publicly support Kesha.'

Adele is by far the most profitable living artist signed to Sony.

Taylor Swift donated $250,000 to Kesha, and Gaga, Clarkson, Miley Cyrus, Fiona Apple and Ariana Grande were among hundreds who posted messages on Instagram and Twitter to the fast-growing #FreeKesha campaign.

Kesha filed a suit against Dr Luke in Los Angeles in October 2014 alleging he had drugged her with a 'sober pill' and raped her shortly after her 18th birthday in California and threatened to take away her publishing rights.

In their countersuit filed last year, Sony actually compared Kesha to Adele, saying that the singer could have a comeback and become just as big as the British chanteuse, adding they had invested $11million into her career and she had collected $3million in royalties during her time at Sony.

Kesha responded to this at the time by saying; 'I love Adele, and this has nothing to do with her or any other artist. I never wanted to have a "comeback" because I never wanted to go away.

'Making these comparisons is Sony's way of trying to put a positive spin on a horribly abusive situation they are supporting.'

Dr Luke meanwhile claims that not only did he not rape Kesha, but that the two never even had sex.

Court documents seen exclusively by DailyMail.com chronicle a decade of alleged abuse and exploitation that left Kesha 'broken, damaged and traumatized.'

She 'lived in a prison of abuse, suffering a psychological and physical fallout so severe as to be described as "life-threatening", requiring her to check into rehab.'

She broke down in court after hearing the judge's ruling back in 2016 before sending out a message to her fans thanking them for the outpouring of support.
