[Chorus]
There's a stranger in my mirror
Who don't know how to behave
He keeps grinnin 'bout you and whistlin' tunes
While he ought to be watchin me shave
We move alike and we look the same,
But I swear we've got totally different brains,
And the love we're in with you,
Just makes it clearer, 
He used to be my twin, 
Now there's a stranger in my mirror

And he doesn't want to go out drinkin,
With all of his friends no more,
He's got both of thinkin, you're what we're livin for
We've gone crazy and we can't recover
You're always on one mind or the other,
I admit we should be certified,
He's a little schizophrenic and so am I, 

There's a stranger in my mirror
Who don't know how to behave
He keeps grinnin bout you and whistlin' tunes
While he ought to be watchin me shave
We move alike and we look the same,
But I swear we've got totally different brains,
And the love we're in with you,
Just makes it clearer, 
He used to be my twin, 
Now there's a stranger in my mirror

And he's always doin' little things,
I never thought I'd do,
Like lookin' at diamond rings,
Drawin' hearts and writin' I love you's,
Thought it was just a case of mild affection
Until I caught a glimpse of my reflection
I looked up into my own eyes
And saw someone startin' back I didn't recognize.

There's a stranger in my mirror
Who don't know how to behave
He keeps grinnin bout you and whistlin' tunes
While he ought to be watchin me shave
We move alike and we look the same,
But I swear we've got totally different brains,
And the love we're in with you,
Just makes it clearer, 
He used to be my twin, 
Now there's a stranger in my mirror

Lord, I'm in love with you,
Now there's a stranger in my mirror
