Drake 's attorneys have finally served an elusive key witness who is accused of using botting tactics to fraudulently inflate numbers on Kendrick Lamar 's "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.
