Sony Music is in the midst of negotiating a split with Dr Luke after years of controversy following Kesha's rape allegation against him, a source told the Hollywood Reporter.
As the Daily Mail reports, Lukasz Gottwald had a long relationship with the company, generating dozens of hits for stars such as Kelly Clarkson, Avril Lavigne and Miley Cyrus.

However, in October 2014 Kesha came forward to accuse Dr Luke of once giving her a date-rape drug and then taking advantage of her in a hotel room.
She alleged that he exerted 'suffocating control' over her life and career for a decade, and that he consistently insulted her looks and denied her some of the profits from her music.
Gottwald later counter-sued Kesha, claiming that she defamed him, and that her attempt to extradite herself from the record and publishing contracts was extortion.
