A number of Twitter users looked to give weight to the wild allegation that Lavigne took her own life in 2003 following the death of her grandfather. The conspiracy says that because Lavigne passed away at the peak of her career, her record company hired a lookalike by the name of Melissa Vandella to impersonate her.
Those running with the conspiracy have looked for proof in the singer's change of appearance throughout the years, pointing out changes in her skin, jawline, makeup style and fashion choices, with one user even going as far as to compare handwriting styles.
Others point to possible clues hidden in the lyrics of Lavigne's songs, while more people feel a promotional photo in which she has the name "Melissa" scrawled on her hand is proof enough.
The theory is thought to have come from a Brazilian blog titled Avril Esta Morta (Avril Is Dead), which a BuzzFeed reporter deemed to have been set up to "prove how easy it is to start a big internet conspiracy theory." You can find some of the internet super-sleuthing below, and take in the entire thread here.
A similar rumour moved around the internet last year concerning Atlanta rap icon Gucci Mane, with fans alleging that the rapper's embrace of a sober, healthy lifestyle meant he had been cloned.
