Pink feels that its "karma" for music producer Dr. Luke for his year-long legal battles with Kesha.
Pink worked with Dr Luke, real name Lukasz Gottwald, which he co-wrote and produced three of her songs from her 2006 album 'I'm Not Dead.'
In an interview with the New York Times, Pink said she doesn't know what's the beef between Dr. Luke and Kesha in regards to the allegations made, which Gottwald has vehemently denied. But, she said, "I know that regardless of whether or not Dr. Luke did that, this is his karma and he earned it because he's not a good person."
"I have told him that to his face and I do not work with him. He doesn't do good business, he's not a kind person, he doesn't do the right thing when given ample opportunities to do so, and I don't really feel that bad for him," she added.
The 38-year-old singer is the latest star to speak up about the producer. Last month, Kelly Clarkson claimed that she lost "millions" because she didn't want to be associated with the producer.
Other artists, who have expressed support for Kesha's legal battle against Dr. Luke, include Taylor Swift, Lady Gaga, Fiona Apple, and Miley Cyrus.
Kesha sued Dr Luke in 2014, accusing him of drugging, raping and verbally, physically and emotionally abusing her.
Dr. Luke has denied Kesha's accusations and countersued for defamation and breach of contract. "I didn't rape Kesha and I have never had sex with her," he tweeted last year.
