Drake is suing his record label for spreading a “false and malicious narrative” when it released and promoted Kendrick Lamar’s diss track “Not Like Us.”

Drake filed a lawsuit Tuesday against his and Kendrick Lamar’s record label Universal Music Group, claiming Lamar’s diss track “Not Like Us” defamed Drake by calling him a “certified pedophile”—a major escalation of the months-long feud between the two rappers.

The leading hip-hop superstar beef has been cranked up another notch, with Drake suing Universal Music Group for defamation over rival Kendrick Lamar’s diss track “Not Like Us.”
