Kelly Clarkson finally has something to say about Dr. Luke.

After a cryptic tweet implying a less-than-stellar opinion of her former producer, the American Idol champ has spoken out about how their most recent work together was not exactly her idea.

"I only worked with him because literally I got blackmailed by my label,” Clarkson said in an interview with Australian radio station KIIS FM. "They were like, ‘We will not put your album out if you don’t do this.’"

Clarkson’s tweet came amid a flurry of support for Kesha, who is currently engaged in a legal battle to get out of her contract with Dr. Luke, aka Lukasz Gottwald. She alleges Gottwald raped and abused her for years after she signed to his label in 2005.

Stars like Adele and Lady Gaga have rallied behind Kesha after a judge blocked a preliminary injunction that would allow her to make music outside of her contract with Gottwald’s label Kemosabe Records, owned by Sony Music Entertainment.

While Clarkson was reluctant to comment specifically on Kesha’s lawsuit, she did offer her own account of working with Gottwald. "He’s not a good person to me. We’ve clashed,” she said. "Obviously he’s a talented dude, but he lied a lot. I’ve run into a couple really bad situations. Musically it’s been really hard for me because he will just lie to people, and it will make the artist look bad."

Gottwald co-wrote and produced Clarkson’s No. 1 hit “Since U Been Gone” with fellow superproducer Max Martin. Both producers also worked on 2005’s “Behind These Hazel Eyes” and 2009’s “My Life Would Suck Without You,” the lead single to Clarkson’s fourth studio album All I Ever Wanted, which came out on Sony Music Entertainment’s RCA Records. That was the last time that Clarkson and Gottwald worked together, and that seems to be the album RCA threatened not to release unless Gottwald got a production credit.

"But [Kesha’s] situation is very different from mine,” Clarkson continued. "He never did anything like that with me...If it’s true, I can’t imagine working with somebody who had done something like that."
