A conspiracy that started on a Brazilian fan website claims that at the beginning of her career Avril Lavigne used a body double whose name is Melissa. Apparently, the singer passed away back in 2003 and the producers were keen to use Mellisa as the new Avril Lavigne. One piece of evidence to this conspiracy theory is the sudden change of Avril’s style (the “real” Avril preferred tomboy looks, and Melissa is definitely more girly). Some fans even believe that there are clues in the songs about Melissa becoming the new Avril Lavigne, such as the lyrics in the song “Slip Away” where she sings ““The day you slipped away was the day I found it won’t be the same”, there is also a creepy photo of Avril where she has the name “Melissa” written on her hand. Weirdly enough, this conspiracy theory has more evidence than most of the other conspiracies in this list. Makes you think.
