Drake vented about his exes during a concert in Melbourne, Australia, before Kendrick Lamar’s Super Bowl halftime performance. Serena Williams and SZA, both of whom previously dated Drake, made appearances on stage with Lamar. Williams danced to Lamar’s Drake diss track, while SZA performed two collaborations with Lamar. Drake is currently in a legal battle with Universal Music Group over the song “Not Like Us,” which was addressed by Lamar during his Super Bowl performance. Lamar and SZA are set to begin a stadium tour on April 19.
