As a matter of fact...

You must not know about me
You must not know about me
I could have another you in a minute
matter fact he'll be here in a minute, baby

You must not know about me
You must not know about me
I will have another you by tomorrow
So don't you ever for a second get to thinking
you're irreplaceable

So since I’m not your everything
How about I'll be nothing
Nothing at all to you
Baby I won't shed a tear for you
I won't lose a wink of sleep
Cause the truth of the matter is
Replacing you is so easy*
