Recording of Lavigne's debut album, Let Go, finished in January 2002.

Lavigne released Let Go in June 2002 in the US, where it reached number two on the Billboard 200 albums chart.

During a performance with the Lennox Community Theatre, Lavigne was spotted by local folksinger Stephen Medd.

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.

The Best Damn Thing (2007), Lavigne's third studio album, reached number one in seven countries worldwide and saw the international success of its lead single "Girlfriend", which became her first single to reach the top of the Billboard Hot 100 in the United States.

Her fourth and fifth studio albums, Goodbye Lullaby (2011) and Avril Lavigne (2013), saw continued commercial success and were both certified gold in Canada, the United States, and other territories.

Lavigne's breakthrough single, "Complicated", reached number one in several countries worldwide and made her the youngest female soloist to have a number-one album in the United Kingdom.

Her second studio album, Under My Skin (2004), became Lavigne's first album to reach the top of the Billboard 200 chart in the United States, going on to sell 10 million copies worldwide.

Although she is now happily coupled up in a new relationship, Avril is still on good terms with her exes and considers them family."They're just good people," she says of Chad and Deryck.

"We had marriages, we lived together, I knew their families, they knew mine, we just stayed close and there's a mutual respect."Avril even teamed up with Kroeger for her new album, Head Above Water."Chad, in particular, we're actually really close, because that was a more recent relationship," she explains.

They spent several months in New York working with different co-writers, trying to forge an individual sound for her.

Sarubin told Hit Quarters that they initially struggled; although early collaborations with songwriter-producers including Sabelle Breer, Curt Frasca and Peter Zizzo resulted in some good songs, they did not match her or her voice.

She later sang on "Temple of Life" and "Two Rivers" for his follow-up album, My Window to You, in 2000.
