Dr Luke has been dropped as head of Sony's Kemosabe Records
Dr Luke is in the midst of splitting with Sony Music, it has been reported.
Sony is said to be "distancing itself" from the musician and producer, whose real name is Lukas Gottwald.
A source told the Hollywood Reporter that both sides are currently negotiating a split, and court papers have revealed that he is no longer CEO of Kemosabe Records, a label owned by Sony.
The page on Sony's website about Dr Luke has also been removed.
His reps have declined to comment.
Dr Luke was behind some of the biggest hits of the past decade, including Katy Perry's I Kissed A Girl and Kelly Clarkson's Since U Been Gone, but became embroiled in controversy when he was accused of sexual assault by Kesha.
Kesha sued Dr Luke in 2014, alleging that he sexually assaulted her and intentionally caused her emotional distress, among other accusations, but her claims were dismissed by a judge last year.
Just last month, Kesha's case was dealt another blow when a judge denied the singer's bid to amend her claims against Dr Luke.
Her amended claims allege that Dr. Luke’s companies broke contracts with her by failing to report and pay royalties.
