During a performance with the Lennox Community Theatre, Lavigne was spotted by local folksinger Stephen Medd.He invited her to contribute vocals on his song, "Touch the Sky", for his 1999 album, Quinte Spirit.Having signed a record deal, and with support from her parents, she left school to focus on her music career.Reid gave A&R Joshua Sarubin the responsibility of overseeing Lavigne's development and the recording of her debut album.In July 2006, Lavigne married her boyfriend of two years, Deryck Whibley, lead singer and guitarist for Sum 41. In school, she was sometimes kicked out of class for misbehaving, her parents supported her singing.Her father bought her a microphone, a drum kit, a keyboard, and several guitars, and converted their basement into a studio; following his own love for music Jean-Claude led the family to church at Third Day Worship Center in Kingston, Ontario, where he often played bass."Don't Tell Me", the lead single off the album, reached the top five in the UK and Canada and the top ten in Australia.
By this time, Lavigne had found that she fit in naturally with her hometown high school's skater clique, an image that carried through to her first album, but although she enjoyed skateboarding, school left her feeling insecure."Complicated" was one of the bestselling Canadian singles of 2002, and one of the decade's biggest hits in the US, Lavigne wrote most of the album's tracks with Canadian singer-songwriter Chantal Kreviazuk, and Kreviazuk's husband, Our Lady Peace front man Raine Maida, co-produced the album with Butch Walker and Don Gilmore.Lavigne said that Under My Skin proved her credentials as a songwriter, saying that "each song comes from a personal experience of mine, and there are so much[sic] emotions in those songs". By the age of 15, she had appeared on stage with Shania Twain; by 16, she had signed a two-album recording contract with Arista Records worth more than million.In 2002 she released her debut album, Let Go, emphasising a skate punk persona in which she has been often referred by critics and music publications as The "Pop Punk Queen" Since her professional debut, Lavigne has sold more than 40 million albums and over 50 million singles worldwide, making her the 3rd-best-selling Canadian female artist of all time, behind Celine Dion and Shania Twain.Lavigne took a break from recording music, pursuing careers in feature film acting and designing clothes and perfumes.
