The song "What the Hell" is by Canadian singer-songwriter Avril Lavigne. It was released on January 10, 2011, as the lead single from her fourth studio album, "Goodbye Lullaby." The song was co-written and produced by Max Martin and Shellback. Avril Lavigne described it as her "personal message for freedom," with themes interpreted as a declaration of independence and personal freedom. The music style is bubblegum pop-punk and synthpop, and the song was well-received, achieving top chart positions in various countries. The music video features Lavigne in playful and rebellious scenarios, including locking her love interest in a closet, stealing a taxi, and performing on stage. It was filmed in 3D and premiered on January 23, 2011. As of 2025, Avril Lavigne is actively touring with her "Greatest Hits Tour," including new shows in North America and a recent single "Young & Dumb" in collaboration with Simple Plan. However, "What the Hell" remains one of her well-known hits from earlier in her career.
