That Girl

Who's that girl?
Where's she from?
No,she can't be the one
That you want
You 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
Then i look again and everything has changed
I'm not dreaming so i don't know why
I don't know why
She's everything i wanna be
I'm the one who made you laugh
Who made you feel
And made you sad
I'm not sorry,for what i did,for who i am
I'm not sorry,i'm not her
By the way...
Who's that girl living my life?
