I remember, I was Mr. Cool
And then that you were just a hot little fool
Then you put your heat in me
Now I'm not how I used to be

'Cause my heart's on fire
It's burning me up
(Burning me up, burning me up)
My heart's on fire
It's burning me up
(Burning me up, burning me up)

Just got a feeling, I could do it over
You gotta go in, now you put it out
I thought I told you not to break that
But you keep turnin' up my thermostat

Now my heart's on fire
It's burning me up
(Burning me up, burning me up)
My heart's on fire
Yeah, it's burning me, burning me
Burning me, yeah

Then you put your heat in me
Now I'm not how I used to be

My heart's on fire
My heart's on fire, yeah

My heart's on fire, my heart's on fire
(Burning me up, burning me up)
My heart's on fire, my heart's on fire
(Burning me up, burning me up)

My heart's on fire, my heart's on fire
(Burning me up, burning me up)
My heart's on fire, my heart's on fire
(Burning me up, burning me up)
