There’s a new girl living on your street
The one that you won’t let me meet
But since she came along, you been treating me wrong
You best be careful, she might break your heart

When I call you, on the telephone
They tell me you’re not home
You’re always next door
Well, don’t you love me no more?
You best be careful, she might break your heart

I realize she’s pretty and someone new
But I ask with tears in my eyes
Don’t let her take my place with you
She’s a new girl, so how can she now to do
The things that mean so much to you
And as soon she’s known, she’ll find a lover for her own
You best be careful, she might break your heart
You best be careful, she might break your heart
