You're a lady, you're an angel,
Bringin' sunshine to my life.
You're closest thing Heaven that I've ever had.
Oh, but sometimes, you're a devil,
When you reach out and dim the lights,
An' I say, mmm mmm, you're so good when you're bad.

You would never hurt anybody,
You're too gentle sweet and kind,
Still I keep on doin' things that make you sad.
But you don't hold out on your feelin's,
When there's lovin' on your mind.
An' I say, mmm mmm, you're so good when you're bad.

I could say that you're the perfect woman,
And if it's not, it's just because of me.
'Cause I'm hung up on the perfect woman,
An' I don't know how I deserve to be.

I see other pretty women,
An' Lord, they still, they look good to me.
An' there are some ladies that can drive some men mad.
But when an angel let's her hair down,
Oh, that's something else to see.
An' I say, mmm mmm, you're so good when you're bad.

An' I say, mmm mmm, you're so good when you're bad.
