Universal Music Group CEO Lucian Grainge called Drake’s defamation lawsuit against the record label “farcical” in a letter to the court, refuting the rapper’s allegations that Grainge was personally behind the release and promotion of Kendrick Lamar’s diss track “Not Like Us.”

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.
