Say you know you don't do love
Never believing in commitment
Say you're not the kind of guy
I don't care about the words you say
I don't really work that way

Get you head over heels
Heart beating out of your chest
Guaranteed you were mine
'Cause you know I do it best
Written all over your face
You're switching places
Make you feel just like a dream

Like nothing you've ever seen
I'll be your worst nightmare, your worst nightmare
I'll be your worst nightmare, your worst nightmare

Now I got you hooked on me
You took the bait so easily
I can see you catching feelings, oh
'Cause now you bought me flowers, babe
I'm playing you at your own game

Get you head over heels
Heart beating out of your chest
Guaranteed you were mine
'Cause you know I do it best
Written all over your face
You're switching places
Make you feel just like a dream

Like nothing you ever seen
I'll be your worst nightmare, your worst nightmare
I'll be your worst nightmare, your worst nightmare

I'll be your worst nightmare, your worst nightmare
Oh, I'll be your worst nightmare, your worst nightmare

I, I, I will
I, I, I, I will
I, I, I will
I, I, I, I will

I, I, I will
I, I, I, I will
I, I, I will
I, I, I, I will

I'll be your worst nightmare, your worst nightmare
I'll be your worst nightmare, your worst nightmare
