Avril Lavigne replacement conspiracy theory

A conspiracy theory that originated in 2011 states that Canadian singer Avril Lavigne died by suicide in 2003, shortly after the release of her debut album, Let Go (2002), and was replaced by a body double named Melissa Vandella. Evidence used to support the theory include changes in Lavigne's appearance between 2003 and the present, supposed subliminal messaging in her follow-up album, Under My Skin (2004), and a photoshoot in which Lavigne has the name "Melissa" written on her hand.
