Celebrity is as celebrity does.
The very fact that you’re asking may indicate:
a) you don’t know either.
b) we are both at a loss as to your identity.
c) you’re not carrying photo I.D and a compact mirror to remind yourself.
This is a nicer problem to have though and easily remedied.
If you’re still in doubt – Crime is useful.
Whoever you are – get yourself arrested.
The area constabulary would be pleased to address you by your given name before miranda-isation.
Getting your misdemeanours and debauchery reported by the local press will provide you with a photo, name in bold and ten facts you can discover in print about yourself.
Above all, don’t fret.
You are a product of your biological creators. You have parents somewhere. And rest assured, you are mortal.
… just in case you were worried you were Thor.
