The song from moulin rouge

Whenever we kiss,
I worry and wonder,
Your lips may be near,
But where is your heart,

It's always like this,
I worry and wonder,
You're close to me here,
But where is your heart..

It's a sad thing to realize,
That you've a heart that never melts,
When we kiss do you close your eyes,
Pretending that i'm someone else..

You must break the spell,
This cloud that i'm under,
So please won't you tell,
Darling where is your heart..
