The weirdest rumour circulating the Internet right now? (Besides Demi Lovato and Poot ?) That Avril Lavigne has been dead for years, and was replaced by her doppelganger Melissa Vandella in 2003. When you scroll through Avril’s Instagram, comments flood her posts begging Melissa to come clean. Take this gem for example: “Your bio says ‘designer’ nope melisaa, Avril didn’t like to design. The jig is up." Right.
