Lavigne co-wrote "Breakaway" with Matthew Gerard, which was recorded by Kelly Clarkson for the soundtrack to the 2004 film The Princess Diaries 2: Royal Engagement. "Breakaway" would later be included on Clarkson's second album and released as the album's lead single. Lavigne covered the Goo Goo Dolls song "Iris", performed with the band's lead singer John Rzeznik at Fashion Rocks, and she posed for the cover of Maxim in October 2004. She also recorded the theme song for The SpongeBob SquarePants Movie. "I made the song a little more edgy", Lavigne said. "There are a lot of loud guitars, and we picked the tempo up a little and sang it with a little more attitude." Lavigne rearranged the song with the help of producer Butch Walker.
