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

[CHORUS] 
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, livin' my life 

Seems like everything's the same around me (around me) 
Then 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 
And 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 not day, it's my night 
By the way, who's that girl 
Livin' my life 
Oh no, living my life
