以下是《I Knew You Were Trouble》的詞曲:
Chorus:
I knew you were trouble when you walked through the door
Said hello and said goodbye to my heart
Wish I could say something to bring you back
And take it from the top, but it never would be
Verse 1:
You were a heartbreaker
A liar and a cheater
But I never got over you
And now you're here with me
But it's not what you seem
I'm not what you're used to
And I don't want to play your game anymore
Chorus:
I knew you were trouble when you walked through the door
Said hello and said goodbye to my heart
Wish I could say something to bring you back
And take it from the top, but it never would be
Bridge:
I remember when you used to hurt me
Now I'm the one calling your name
And now we're here together
And I don't know what to say
I don't know what to do
I never thought that I'd be back here with you
Chorus:
I knew you were trouble when you walked through the door
Said hello and said goodbye to my heart
Wish I could say something to bring you back
And take it from the top, but it never would be
Outro:
Now I'm in a whole other world of you
And I'm so glad that I let you in
But now I'm letting you out of my life forever
So bye-bye trouble, see you never again.
