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

[Chorus: Taylor Swift & Kendrick Lamar]
'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 (Uh)
You made a really deep cut (Uh)
And, baby, now we've got bad blood, hey

[Build]
I'm just calling to say

[Drop]
You trippin'
