Is Avril Lavigne Dead?

This theory lingered for years, but interest in it surged when Twitter users around the world made #notmyavril trend. The idea is a pretty dark one. Essentially, Lavigne committed suicide in 2003, and the freakishly similar body double she had employed to appear at some public events carried on in her place, at the behest of Lavigne’s record company. Believers argue that the switch explains the star’s poppier look and sound, but can anything explain that marriage to Nickelback’s Chad Kroeger?
