I, I won't shut you out
Let me in, pretty baby
I, I won't let you down
Oho, it's a sin, pretty baby
It's a sin, pretty baby

I believe in you
Since the time we're together
I believe in you
When you say that you love me
When you say you need me
A whole life through

I believe in you
Take me into your heart
Let me in, pretty baby
Into your life, my love

True, truly I must say
Ooohooohooo, you're the one, pretty baby

True, true love 's here to stay
We'll have fun, pretty baby
We'll have fun, pretty baby

I believe in you
From now on 'till forever
I believe in you
When you say that you love me

When you say you need me
A whole life through

I believe in you
I won't leave you alone

It's a sin, pretty baby

It's a sin, pretty baby
I can't make it alone
I can't make it alone
