This claim is not only false, but visibly satire. The author of this article makes it clear through her tone and her "sources" that this claim is not meant to be taken seriously. The original claim is said to have resurfaced on twitter, but the actual claim originated from a Brazilian fan page back in 2005. According to Metro.co.uk, the fan that leveled these claims backtracked, writing that it was a way of showing how conspiracy theories may seem true. "Many people believe everything they see on the internet, but is this really, right? Avril Lavigne has never died, has never been replaced by a look-alike, I just created this theory and thousands of people believed that this was a fact". Additionally, an article from VICE explains how when Avril released "Hello Kitty" many fans were confused because of the seemingly drastic change to her style and that's why the theory of her being replaced by a body double took hold so fast. "The Avril Lavigne behind the abhorrent slumber-party hit “Hello Kitty” is not the same Avril Lavigne behind “SK8R Boi, because, dear readers, the Avril Lavigne behind “SK8R Boi” is dead and was replaced with an actress shortly after the release of her seminal debut album "Let Go" ". Once again, another author using conspiracy theorists "reasoning" to show how unfounded fans' claims are. A general internet search about this conspiracy leads down a rabbit hole of similar sounding explanations that have no actual facts to back them up. The New York Times wrote about Lavigne's appearance on the "Call Her Daddy" podcast where "She also used the appearance to tell fans that she is alive and herself. And that she was most definitely not replaced by a body double named Melissa Vandella after dying more than 20 years ago".
