Avril Ramona Lavigne

• 2004–05: Under My Skin
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.
Lavigne's second studio album, Under My Skin, was released on 25 May 2004, debuting at No. 1 in several countries, including Australia, Mexico, Canada, Japan, the UK, and the U.S. The album has sold more than 10 million copies. Lavigne wrote most of the album's tracks with Canadian singer-songwriter Chantal Kreviazuk. Kreviazuk's husband, Our Lady Peace front man Raine Maida, co-produced the album, along with Butch Walker and Don Gilmore. Lavigne went on the Live and By Surprise twenty-one-city mall tour in the U.S. and Canada to promote the album, accompanied by her guitarist, Evan Taubenfeld. Each performance consisted of a short live acoustic set of songs from the new album. At the end of 2004, Lavigne embarked on her first world tour, the Bonez Tour, which had stopovers in almost every continent and lasted for the entire 2005 year.
“This record definitely proves that I'm a writer and people can't knock that, because each song comes from a personal experience of mine, and there are so much emotions in those songs. ”
