The top producer has been embroiled in a bitter fracas with the "Tik Tok" star, who was recently denied her bid to terminate her contract with Sony and its subsidiary, Luke's Kemosabe Records, despite accusing the hitmaker of sexual and emotional abuse, reported Rolling Stones magazine.
An attorney for Luke insists the reports of his split from Sony are false, and he is still signed with the top label.
"This is not true. Luke has an excellent relationship with Sony. His representatives are in regular contact with executives at the highest levels at Sony and this has never come up," his lawyer said in a statement.
