Avril Lavigne recently performed at Warped Tour. She was joined on stage by her ex-husband Deryck Whibley from Sum 41, in a statement shared on Instagram.
The pop-punk star reflected on her headlining performance and the special guest appearance during the show.
“Headlined Warped Tour last night and it was everything I would have expected and more!” Lavigne said. “It was one of the best crowds and you guys know how to rock.”
She also highlighted the collaboration with her former spouse during the performance.
“Also this legend, Deryck Whibley from Sum41, joined me for one of the best pop punk anthems of all time ‘In Too Deep,'” she continued.
The reunion marks a notable moment as the former couple performed together on one of punk rock’s most iconic songs.
This collaboration represents more than just a musical moment. It highlights the enduring professional relationship between two prominent figures in the pop-punk scene.
Apple Music reported that this appearance at the Warped Tour was part of Avril Lavigne’s 2025 Greatest Hits Tour. The tour features a blend of her classic songs and collaborations with prominent pop-punk artists, emphasizing her lasting influence in the genre. The tour has been designed to celebrate her two-decade career in music while showcasing her connections within the punk rock community.
The setlist from the Warped Tour performance included Lavigne’s biggest hits like “Girlfriend,” “Complicated,” and “Here’s to Never Growing Up,” as documented by Setlist.fm. The inclusion of Sum 41’s “In Too Deep” performed with Whibley added a special element to the show. It bridged the gap between two influential acts from the early 2000s pop-punk era.
Lavigne and Whibley were married from 2006 to 2010. Their relationship was closely followed by fans of both artists during the height of their respective careers. Setlist.fm noted that this marks one of the rare occasions where the former couple has shared the stage since their divorce. This makes the performance particularly significant for longtime followers of both Sum 41 and Lavigne’s music.
The performance demonstrates how personal relationships in the music industry can evolve into lasting professional collaborations, even after romantic partnerships end. Both artists have continued to maintain successful careers in the pop-punk genre. Sum 41 recently announced their farewell tour and Lavigne continues to tour extensively with her greatest hits collection.
