Dr Luke not a good person: Kelly Clarkson

Los Angeles: Singer Kelly Clarkson has slammed her former collaborator producer Dr Luke, who has been accused of raping singer-songwriter Kesha.

The 33-year-old former 'American Idol' winner, who collaborated with the producer on her hits like 'Since You Been Gone' and 'Behind the Hazel Eyes', had nothing nice to say about him when she weighed in on his legal battle with Kesha, reported Aceshowbiz.

"Her experience was different to mine. Her fans are like, 'Why don't you stick up for her?' but I wasn't there," Clarkson said.

"I'll be honest about the guy, but I don't know that situation. He's not a good person, to me. We've clashed."

Of why she collaborated with him despite her dislike of him, Clarkson revealed that she was forced to do it by her label.

"I only worked with him because literally I was blackmailed by my label," she said and went on claiming that her label threatened they wouldn't release her album if she didn't work with him.

A number of fellow musicians showed support to Kesha on social media, after a judge last month denied to release Kesha from her contract with Luke's Kemosabe Records, which is a subsidiary of Sony Music.
