Don't know what you're trying to do
But I think that I am on to you
Don't know why you're trying to hide
What you got on the side

Well, I never, never, never know what you're up to
Baby, I'm on to you, you know that I'm on to you
Baby, I'm on to you

If you're keepin' secrets from me
I don't wanna hang around
Baby, it's no mystery
You've been out on the town

Well, I never, never, never know what you're up to
Baby, I'm on to you, you know that I'm on to you
Baby, I'm on to you

You never try to hide it
And you don't even lie
So that's why I've decided
That I might say goodbye

But if you can show me different, lighten up your act
You can show me different, prove to me you're on the right track
Loneliness can break a heart
But that's never gonna happen to me
I will make a brand new start
'Cause that's the way it's got to be

Well, I never, never, never know what you're up to
Baby, I'm on to you, you know that I'm on to you
Baby, I'm on to you

Don't know what you're trying to do
But I think that I am on to you
Don't know why you're trying to hide
What you got on the side

Well, I never, never, never know what you're up to
Baby, I'm on to you, you know that I'm on to you
Baby, I'm on to you
