With everything happening today
You don't know whether you're coming or going
But you think that you're on your way
Life lined up on the mirror don't blow it
Look at me when I'm talking to you
You looking at me but I'm looking through you

And I don't see nobody else
I see myself I'm looking at the

[Bruno Mars:]
Mirror on the wall, here we are again
Through my rise and fall

Light it up, that's smoke in mirrors
I even look good in the broken mirror
I see my momma smile that's a blessing
I see the change, I see the message
And no message could've been any clearer
So I'm startin' with the man in the...

[Bruno Mars:]

[Bruno Mars:]
You told me that they can understand the man I am
So why are we talkin' to each other again?

[Lil Wayne:]
Uh...

Mirror on the wall, here we are again ([Wayne:] yeah)
Through my rise and fall
You've been my only friend ([Wayne:] Any questions?)
You told me that they can ([Wayne:] I come to you) understand the man I am ([Wayne:] You always have the answer)
So why are we here talkin' to each other again?

[Bruno Mars:]
Mirror on the wall.

[Wayne:]
Ay, B.P.
Looks like I did take 'em to Mars this time

[Bruno Mars:]
(So why are we talking to each other again?)
