Lucian Grainge, CEO of Universal Music Group, slammed Drake’s allegation that he was personally behind the release and promotion of Kendrick Lamar’s chart-topping diss track “Not Like Us” in a letter to the court.

In a discovery bid, Drake, born Aubrey Graham, urged the court to force UMG and chief executive Lucian Grainge to turn over the label’s contract with Lamar, as well as information relating to allegations of domestic violence and other crimes committed by the Compton rapper.
