Tough People

Pop-punk icons Avril Lavigne and Deryck Whibley reunited onstage over the weekend for a surprise performance of Sum 41’s “In Too Deep” during Lavigne’s headlining set at the Vans Warped Tour stop in Washington, D.C.

Eight songs into her June 15 set, Lavigne brought out her ex-husband — and Sum 41 frontman — to deliver one of the most iconic anthems of the genre. “What do you say we bring one of the OG Warped Tour bands back out here tonight to join me right now?” she told the crowd. “Let’s hear it for Deryck from Sum f—ing 41!”
