Christina:
Oh oh oh oh oh oh oh oh oh oh
Oh oh oh oh oh oh oh oh oh oh

Mike:
Be careful making wishes with the d-d-d-dark
Can't be sure when they fit their m-m-m-mark
And besides in the mean mean time i'm
Just dreaming of tearing you apart

I'm in the deep deep dance with the devil
You know the world can never get me on my level
I just got to get you out the cage on my own lovers range
God I need a spark to ignite

Christina:
Ohhhhh
This girl is on fire
This girl is on fire

Mike:
(Light 'em up, up, up
Light 'em up, up, up
Light 'em up, up, up)

Both:
I'm on fire

Christina:
Oh oh oh oh oh oh oh oh oh oh

Mike:
In the dark, dark

Christina:
This girl is on fire

Mike:
In the dark, dark

Christina:
Looks like a girl but she's a flame
So bright she could burn your eyes
You better look the other way
And you can try but you'll never forget her name
'Cause she's on top of the world
The hottest of the hottest girls
Say ohhhhh
This girl is on fire
This girl is on fire

Mike:
(Light 'em up, up, up
Light 'em up, up, up
Light 'em up, up, up)

Both:
I'm on fire

Christina:
Oh oh oh oh oh oh oh oh oh oh

Mike:
In the dark, dark

Christina:
This girl is on fire
Yeahhh
'Cause my song kno-o-o-o-ow
What you did in the dark
Fire

Mike:
(Light 'em up, up, up)
Light 'em up, up, up
Light 'em up, up, up)

Christina:
This girl is on fire

Mike:
(Light 'em up, up, up
Light 'em up, up, up
Light 'em up, up, up)

Both:
I'm on fire

Christina:
Oh oh oh oh oh oh oh oh oh oh

Mike:
In the dark, dark

Christina:
This girl is on fire

Mike:
In the dark, dark

Both:
Oh oh oh oh oh oh oh oh oh oh
