During her When We Were Young set in Las Vegas, Avril Lavigne brought out Simple Plan for a live performance of their 2025 collaboration “Young & Dumb.” The two Canadian acts, who toured together earlier this spring and summer, have shared a long history as peers in the pop-punk scene, and they’re never afraid to bring it to the WWWY stage.
