Avril Lavigne is her generation's Paul McCartney

You know there are too many conspiracy theories when people are reduced to claiming that Avril Lavigne died and was replaced by an imposter in 2003:

A Brazilian blog post goes into an extreme amount of detail, looking at differences between 'old' Avril and 'new' Avril including height ("Avril was 1.58m in 2002 and now it's 1.55m - it's impossible!"), voice ("the double is soprano"), and even her nose and freckles.

"They are different physically, although they are almost identical," the conspiracy theorist wrote. "After all, they are lookalikes."

And apparently Avril changing autographs and fashion style is another piece of 'proof' that the Avril today is not the same as the one from more than 13 years ago.

You could just about see why The Beatles might have gone to the trouble of bringing in a ringer for Paul McCartney when he died at the age of 28, although nobody has ever explained why they'd have gone to all that subterfuge and then give the game away by effectively releasing an album sleeve with the words "THAT'S NOT THE REAL PAUL WE HAVE DONE A TRICK" all over it.

But had Avril needed to be replaced in 2003? Wouldn't you just have gone with someone else who could be a bit like Pink?
