The famous producer, who is embroiled in a legal battle with Kesha, who claims he sexually assaulted her while recording music together, is getting slammed by the "Piece by Piece" songstress, who claims she was forced to work with him.
"The last time I worked with him I got blackmailed by my label," she explained on Australia's Kyle & Jackie O Show. "They were like, 'We will not put your album out if you don't do this.' It was really hard for me. I try to make the best of the situation."
Dr. Luke, whose real name is Lukasz Gottwald, worked with the American Idol winner on her hits "Since U Been Gone" and "My Life Would Suck Without You."
Even though she admits he is good at what he does, she also explained that working with him put a strain on her given his negative attitude toward artists. "He's not a good person, to me. We've clashed before. He's difficult to work with, he's kind of demeaning," she said.

But a source tells E! News that Kelly wished to work with Dr. Luke on more than one occasion. "Luke was asked to work with her and that Kelly had actually returned to do more music with him," the source said.
E! News has reached out to a rep for Kelly for comment.
Despite her own issues with Luke, Clarkson clarified that she never experienced any of what Kesha alleges in her lawsuit, saying he "never did anything like that to me."
Luke has continuously denied all of Kesha's accusations, posting on Twitter, "I didn't rape Kesha and I never had sex with her." He also claims her lawsuit is "motivated by money."
Stars such as Lena Dunham and Adele have shown their support for the "Die Young" singer publicly, so when Clarkson was asked why she hasn't stepped forward she said that she really didn't know the full situation. "I'll be really honest about that guy but I don't know that situation," she explained. "If it is true I can't imagine working with someone that had done something like that."
At the end of the day, however, Clarkson worked with Luke because she didn't want to hurt everyone else involved. "We have a whole crew to support and you know we have our whole touring crew, people that depend on us for their livelihood," she said.
"Sometimes you have to make decisions that you just have to swallow that pill."
