Hilary Duff

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
But 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
