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.”

Drake alleges UMG played a central role in boosting the chart-topping Interscope Records single, which labeled him a “certified pedophile” during his public feud with Lamar. Interscope, Lamar’s label, operates under UMG, as does Drake’s own label, Republic Records.
