Lyrics:

I've heard the rumors going round the town
You think you're playing me for a fool
But everybody's seen you sneaking around
You and baby sister thinking you're so cool

You used to love me
Till you met my baby sister
You used to love me
Till you met my baby sister

The trouble started when
I brought you home to meet my friends and family
The love you had for me went right out the door
When you saw my baby sister in her tight blue jeans

You used to love me
Till you met my baby sister
You used to love me
Till you met my baby sister

Well, I know I shouldn't be blaming only you
I'm sure my baby sister played her part
But then the worst of my nightmares all came true
Just like a knife in my heart
I saw you both in the dark
Baby sister

So when you take her to your mountaintop
To show her what your love's about
I hope the moon is shining extra bright
'Cause that's where you'll be living when my daddy finds out

You used to love me
Till you met my baby sister
You used to love me
Till you met my baby sister

She's so cool in her tight blue jeans
Gonna be in trouble when our daddy finds out
She's so cool in her tight blue jeans
Gonna be in trouble when our daddy finds out
She's so cool in her tight blue jeans
Gonna be in trouble when our daddy finds out
She's so cool in her tight blue jeans
Gonna be in trouble when our daddy finds out
You used to love me
Till you met my baby sister
