NO, SHE IS NOT DEAD! It's was all a hoax some stupid idiot made, he thought it was fun but he got scared and stopped it from trending after Avril Lavigne fan started threatening him. I have to say he was pretty smart to come up with all those ideas but it's really a slap in Avril Lavigne fan's faces, there was a same case as Paul McCartney's.
And as a Avril Lavigne fan, we all know no one can replace her; not even a look-alike can. If anda want a straight answer, well then; Avril Lavigne is still alive and well. And lastly, I hope this stupid hoax will not be brought up anymore. Thanks.
