Kelly Clarkson may have teamed up with hit music producer Dr. Luke in the past, but in a new interview, the singer-songwriter says she was "blackmailed" into the partnership.

Dr. Luke (real name Lukasz Gottwald) is currently embroiled in a legal battle with former popstar collaborator Kesha (Kesha Rose Sebert) over her allegations that he sexually, physically and verbally abused her over a period of years.

Artists who have worked with Dr. Luke

  • Kelly Clarkson
  • Pink
  • Avril Lavigne
  • Katy Perry
  • Britney Spears
  • Nicki Minaj
  • Rihanna
  • T.I.
  • Miley Cyrus
  • ​Ne-Yo
  • Shakira
  • Pitbull
  • Kesha

Though Clarkson declined to comment on Kesha's claims, she blasted the hit producer — who has also worked with Katy Perry, RihannaPitbull and Miley Cyrus —  as "poor of character."

"A lot of artists that have worked with him don't work with him anymore for pretty good, solid reasons," Clarkson said during an interview Sunday on Australia's KIIS FM The Kyle & Jackie O Show. 

"He's not a good person to me. We've clashed. I can't really say anything other than that." 

In Clive Davis' 2013 biography, the music mogul wrote that he coordinated the collaboration between Clarkson and Luke, who have worked together on hit tracks such as Since You've Been Gone and My Life Would Suck Without You.

"Musically, it's been really hard for me because he will just lie to people and it makes the artist look bad," the former American Idol winner told the Australian radio show.

"Even the last time I worked with him I only worked with him because literally I got blackmailed by my label," Clarkson said. 

"They were like, 'We will not put your album out if you don't do this.'"

In late February, Kesha lost a legal bid to be freed from her contract with Dr. Luke and Sony Music Entertainment. 

According to her lawyers, the singer's current contract — which comprises a five-album agreement, with Luke producing at least six songs on each album  — has stalled her career because she refuses to work with him. 

Following the ruling, many performers have expressed support of Kesha, with pop star Taylor Swift donating $250,000 US to pay for the Tik Tok, We R Who We R and Die Young singer's ongoing legal fees.
