Kelly Clarkson recently slammed music producer Dr Luke claiming that she had no choice but to work with him.
In a recent interview, the 33-year-old songstress revealed that she only worked with Dr Luke because she got blackmailed by her label, reports News.com.au.
She added that her label told her that they will not release her album if she doesn't work with Dr Luke.
Dr Luke, whose real name is Lukasz Gottwald, co-wrote and co-produced one of Clarkson's biggest hits, 'Since U Been Gone.'
He is currently locked in a legal battle with Kesha, who claims he sexually assaulted her.
