Avril has been a Canadian superstar since she was 16 years old. Avril got her start in the music industry when she won a competition to perform alongside Shania Twain. Although, she was discovered by her first manager when she was singing covers at a Chapters store in Kingston.
Her first two albums were incredibly successful. On Let Go and Under My Skin, she had many singles from both. She called herself a "tomboy" and a "rebel", which were shown through her baggy pants and her ties.
Her latest record The Best Damn Thing has been heavily criticized because many artists and songwriters claim that Avril had stolen their songs.
For her third studio album, she completely changed her image. Once

she was a bad-ass tomboy, and now she is a pop princess. Her whole album was different from her original persona. Songs lacked meaning like her earlier ones, and were more about how she is “The Best Damn Thing”, and how a guy should ditch his girlfriend for her.
When her first single “Girlfriend” was released from her 2007 album The Best Damn Thing, she was accused of plagiarizing it from the 1970's song “I Wanna Be Your Boyfriend” by The Rubinos.
Lavigne's lyrics go:
"Hey, hey, you, you, I don't like your girlfriend; No way, no way, I think you need a new one; Hey, hey, you, you, I could be your girlfriend!"
Whereas The Rubinos I Wanna Be Your Boyfriend go:
"Hey, You, I Wanna Be Your Boyfriend".
Not only are the lyrics extremely similar, but the beat of both songs are almost the same.
Avril claims she has never heard that song in her life, and that just because a few lyrics are similar it doesn't mean she plagiarized it. She said she shouldn’t be blamed for plagiarizing it based on the same five words. She also claims she has been falsely accused.

Not only has Avril been accused of plagiarizing “I Wanna be Your Boyfriend”, but singer-songwriter Chantal Kreviazuk claims she wrote the song “Contagious” with Avril, but Avril didn’t give her any credit for the song. Chantal says that Avril, “crossed the ethical line and no one says anything. That's why I'll never work with her again”. Avril says in her defence that Chantal did send her a song titled “Contagious” a few years ago, but it got pushed aside. A few years later, her and her friend Evan began to write songs for his album, and wrote a song called “Contagious”, but with different lyrics, meaning and melody.

So, who dunnit?
Did Avril really use the song Chantal sent her a few years back and didn’t credit her for it, or did Avril just have a song on her new record with the same title?
Not only is Chantal pointing fingers huge, but many of the songs on Avril's album sound uncannily alike. For example, the songs on her CD: "Girlfriend", "I Can Do Better", "Runaway", "The Best Damn Thing", "Hot", "I Don't Have To Try", "Contagious" and "Keep Holding On" all sound (in some way) similar to another previously release song- not done by Avril.
