Considered one of the most popular conspiracy theories of the 21st century, it has become a popular debate as to whether or not Avril Lavigne is the same person she was back in 2003. The theory is that Avril Lavigne committed suicide in 2003 and was replaced by a lookalike named Melissa Vandella. The main proof for this theory is that her voice sounds slightly different from her first album. Additionally, Avril used to wear trousers and boyish clothing until 2003 when her style drastically changed to skirts and dresses. Another proof of this concept is the far-fetched hints in lyrics from her later songs.
