Lyrics:

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
