Originally sending Avril Lavigne the song in 2005, Kreviazuk would go on to accuse Lavigne of plagiarism in regards to the track. She stated that “I sent her a song two years ago called ‘Contagious,’ and I just saw the track listing to [The Best Damn Thing] and there’s a song called ‘Contagious’ on it and my name’s not on it. What do you do with that?”. Kreviazuk would later retract this statement clarifying that the “Contagious” on The Best Damn Thing was a different song from the aforementioned track that she sent Lavigne.
