There were places we would go, at midnight,
There were secrets that nobody else would know,
There's a reason but I don't know why,
I don't know why,
I don't know why,
I thought they all belonged to me,

Who's that girl?
Where's she from?
No she can't be the one,
That you want,
That has stolen my world,
It's not real, it's not right,
It's my day, it's my night,
By the way,
Who's that girl, living my life?
Oh no, living my life.

Seems like everything's the same, around me,
When I look again and everything has changed,
I'm not dreaming so I don't know why,
I don't know why,
I don't know why,
She's everywhere I wanna be,

Who's that girl?
Where's she from?
No she can't be the one,
That you want,
That has stolen my world,
It's not real, it's not right,
It's my day, it's my night,
By the way,
Who's that girl living my life?

I'm the one who made you laugh,
Who made you feel,
Who made you sad,
I'm not sorry,
For what we did,
And who we were,
I'm not sorry,
I'm not her,

Who's that girl?
Where's she from?
No she can't be the one,
That you want,
That has stolen my world,
It's not real, it's not right,
It's my day, it's my night,
By the way,
Who's that girl living my life?
Oh no, living my life.
