Avril Lavigne was replaced by a body double.
In the wake of her debut album, Avril Lavigne reportedly hired a body double, Melissa Vandella, to deal with all the paparazzi attention. The two became close friends, and when Avril died (wait what?) Vandella apparently stepped in for her.
The Brazilian fan site avrilestamorta.blogspot.com (yup, that means what you think it means) points to Avril’s sophomore album Under My Skin, which contains such portentous track titles as “Nobody’s Home,” “Take Me Away,” and “My Happy Ending.” Conspiracy theorists also reference variations in her height and skin blemish patterns to prove that the Avril on stage today is actually Vandella.
