Lyrics:
[Chorus]
Cause baby, now we've got bad blood
You know it used to be mad love
So take a look what you've done
Cause baby, now we've got bad blood, hey!
Now we've got problems
And I don't think we can solve 'em
You made a really deep cut
And baby, now we've got bad blood, hey!

[Verse 1]
Did you have to do this?
I was thinking that you could be trusted
Did you have to ruin what was shiny?
Now it's all rusted
Did you have to hit me where I'm weak?
Baby, I couldn't breathe
And rub it in so deep
Salt in the wound like you're laughing right at me

[Pre-Chorus]
Oh, it's so sad to
Think about the good times
You and I

[Chorus]
Cause baby, now we've got bad blood
You know it used to be mad love
So take a look what you've done
Cause baby, now we've got bad blood, hey!
Now we've got problems
And I don't think we can solve 'em
You made a really deep cut
And baby, now we've got bad blood, hey!

[Verse 2]
Did you think we'd we be fine?
Still got scars in my back from your knives
So don't think it's in the pa.
